Way behind on sharing this, but better late than never.
The Mayo Clinic Libraries’ Liblog has a screencast by Melissa Rethlefsen on PubMed’s new Advanced Search features that you can embed on your own page:
In case I have not mentioned it recently: Melissa is awesome.
Got my hands on my copies of the book today! How exciting!

Yay!
You can buy a copy from:
Springer Publishing
or here:
I’m looking forward to eventually seeing it in WorldCat.
Congratulations to Melissa Rethlefsen (who wrote a heck of a lot more than I did)! You should really go email Melissa now and tell her how much she rocks.
I subscribe to a bunch of mailing lists because they frequently contain useful information, but being subscribed to these lists using the email account provided by our hospital would be problematic. The volume of postings on some lists would clutter up the acount, making it more difficult to manage and making it more likely I’d miss other, more important emails from inside our organization.
So I subscribe to lists using a Gmail account. Here’s why:

Bonus tip: Would you rather read your list email information in your feed aggregator? Set your lists Gmail account to forward the emails to MailBucket, and MailBucket will give you the content in an RSS feed.

To make sure I don’t miss any online chatter about Computers in Libraries 2008 (which starts next Monday), I’m subscribed to the following feeds:
If you’re like me, you’d rather subscribe to one feed than several, so all the feeds above are included in the feed below:
Single feed that combines all of the above:
http://feeds.feedburner.com/Cil2008Superfeed
Grazr widget below will let you browse the Superfeed contents:
You’ve probably heard about ReadBurner by now.

The idea behind ReadBurner is that it aggregates counts of items that are frequently shared in Google Reader.
First a point of clarification: ReadBurner doesn’t get its data directly from Google Reader in aggregate via an API- it gets the data from the RSS feeds of public linkblogs fed by Google Reader. This is explained on ReadBurner’s About page:
“ReadBurner aggregates items that are shared on the Google Reader.
This works by constantly updating RSS feeds of currently several hundred linkblogs. In order to filter out the best stuff ReadBurner counts, whenever an item is shared by multiple persons.”
ReadBurner’s creator, Alexander Marktl, allows users to submit new linkblogs (or does he?), but he can’t ever gather all of them…so I suspect that ReadBurner won’t ever really represent the sharing habits of Google Reader users. Further, I find it hard to believe that Google would not be working on a similar project that actually will have access to all the sharing data from Google Reader users in its entirety…at which point ReadBurner will stop being interesting.
In the meanwhile, ReadBurner is still pretty neat. The features I’d most like to see added are search and to have searches outputted as RSS feeds. I’ve had no luck getting ReadBurner to output the feeds I want, but I have managed to make it filter for just the stuff I want.
I really wanted a form so I could search and, for instance, see if any posts at this blog were being frequently shared. Sadly, no such search form exists at ReaderBurner.
Fortunately, we can make it search in a limited fashion even without a form by messing with the URL a bit.
The back end of ReadBurner is PHP/MySQL, a combination I gained some familiarity with through working on LibWorm with Frankie Dolan (and by using WordPress to power this blog).
All our little hacks will start from this URL:
http://www.readburner.com/index.php?
From here, we can play with two parameters, r and a.
r = The name of the source the item came from
a = The name of the author of the item
So if we wanted to see items in ReadBurner that were shared from davidrothman.net, we just need to tack r=davidrothman.net onto the end of http://www.readburner.com/index.php? like so:
http://www.readburner.com/index.php?r=davidrothman.net
For another example, shared items from Boing Boing could be found like so:
http://www.readburner.com/index.php?r=boing%20boing
But what if we want only to see shared items items from Boing Boing which were authored by Cory Doctorow?
To our existing http://www.readburner.com/index.php?r=boing%20boing, we’ll tack on &a=Cory%20Doctorow1, giving us:
http://www.readburner.com/index.php?r=boing%20boing&a=Cory%20Doctorow
Marktl himself shows how to tweak the URL of ReadBurner to filter for language and for a minimum number of shares.
Of course, there are easier ways to get this kind of info from ReadBurner. Once could subscribe to the feed for the recently submitted items and then filter using Yahoo! Pipes or one of the other free tools for filtering RSS feeds…but that’s not as much fun.

A few days ago I made a Google Custom Search Engine for searching the Web sites of medical libraries.
Connie Schardt pointed out that it could be useful for finding handouts, tutorials and other teaching materials. Here are some ideas on how this might be done.
Your turn: What other searches would be useful?
Berci asked:
David, do you know how can we subscribe to searches on Youtube? I mean, I’d like to follow the RSS feed of the search term genetics on Youtube, for example.
Jan answered:
You can create RSS feeds for tags. FI: rss for genetics will be http://www.youtube.com/rss/tag/genetic.rss.
For search related rss-feeds on YouTube you could try referd.info.
The feed that Jan suggests will only contain videos that have been tagged “genetic.” It won’t contain videos that have the word “genetics” elsewhere in their metadata.
To capture videos that have “genetics” anywhere in their metadata, try this feed:
http://www.youtube.com/rss/search/genetics.rss
Unfortunately, this simple way of creating a search-based YouTube feed (http://www.youtube.com/rss/search/[search terms].rss) will limit the search results to 20 items.
If we want to get more than 20 results in our feed, we need to use the YouTube API, which is powerful and not especially difficult to play with.
If we want a feed that captures the most recent 50 videos, we can use this feed:
http://gdata.youtube.com/feeds/videos?vq=genetics&max-results=50&orderby=updated
Neat, huh? Still, I don’t subscribe to these sorts of feeds.
Unfortunately, both the feed for the tag “genetics” and the feed for the search term “genetics” are too full of junk (including spammy, awful ringtone advertising) for me to deal with efficiently. I once had search feeds like these from YouTube fed into LibWorm, but removed them because the results returned for the search term “library” were frequently inappropriate and wildly distant from Librar*/LIS topics.
If one was determined to make such a feed useful, one could use a tool like Yahoo Pipes to filter out the worst and most obvious of the junk items, producing a feed like this one. It is far from perfect, but most of the junk is gone and little of the good stuff is missing.
(Please feel free to copy this Pipe.)
However, a Pipe used for this purpose would probably need semi-routine maintenance and updates to its Filter module to keep the junk out.1
Okay, that was fun! Any other feed questions?

It looks like the article I wrote for the Journal of Hospital Librarianship is going to appear in print in Volume 7, Issue 3.
My hope was that this article would be a painless, step-by-step guide to help the medical librarian set up and start using an aggregator right away.
Many health sciences library staffers who might benefit tremendously from the utilization of an RSS aggregator are intimidated by the mistaken impression that setting up and using a feed aggregator is difficult or requires technical knowledge. The truth is that anyone who can use an e-mail client can quickly learn to manage an aggregator, and can begin benefiting from its use right away. This article seeks to walk the less technologically inclined health science library staffer through the necessary steps to begin reaping the benefits of utilizing RSS feeds, including setting up an aggregator, finding useful feeds, subscribing to feeds, and managing them. This is accomplished with only an absolute minimum of geekspeak or technobabble.
It occurred to me recently that I haven’t written a how-to post in a good while.
The primary reason for this is that I don’t have a good idea what sorts of how-to posts would be most welcome or useful to readers. If you have a technology question or a how-to you’d like to see, please leave a comment (anonymous is okay, if you prefer) or drop me an email and let me know?
[EDIT] Please disregard the criticisms of EBSCO’s policies in the latter part of this post. They were not explained or understood well. See this post for clarification.[/EDIT]
____________________________
I was in the process of writing detailed instructions on how to use the new RSS features in EBSCOhost when I saw Paul Pival’s kick-butt screencast.
Paul has posted a larger, higher-quality version here.
EBSCO’s announcement: EBSCOhost RSS Feed and Search/Journal Alert Upgrades
Okay, this is an improved interface for feeds, mostly because the feeds are easier to find. However, Ken Varnum and Paul both point out the regrettable policy EBSCO has put in place by which feeds will be deleted if they are inactive for two months or if they are not accessed within a week of creation. With apologies to the very nice people I know at EBSCO, this is an extremely unwise policy.
The POINT of search-based feeds is that the user doesn’t have to come back and CHECK every two weeks for new hits. Forcing the user to come back to the site sort of defeats the purpose of the feeds.
Dear EBSCOfolk-
Feeds make it more likely that people are going to actually USE your service and increase usage stats. Feeds cost you very little in resources. They buy goodwill and convenience for the user at extremely low cost.
A number of resources I can access through EBSCO are also available (at my local academic library) through other vendors. If you’re going to make it so dang inconvenient, I (as a user) will create search feeds for those resources through your competitors’ services and access the full text through your competitors’ services.
Please consider instead just requiring the user to confirm his/her wish to continue the feed annually. If you like, you can even send an item down the feed every week to say “no new hits.”
While this policy is in place, RSS feeds in EBSCOhost’s RSS “enhancements” are, I’m sorry, next to useless for my purposes.
PubMed already has feeds, OVID is going to roll them out this year. EBSCO Medline fulltext is going to look ridiculous if this doesn’t change. Feeds are a current awareness tool, just like the emailed alerts. PLEASE stop crippling their usefulness.
Update: Wow!ter is absolutely right- his variation is better.
Query: +(CIL2007 “CIL 2007″ “computers in libraries”)
Feed for this query
______________________________________
Its great that so many bibliobloggers are posting about Computers in Libraries 2007, but it can be a lot to keep up with. An easy way to keep up with all the posts is to use LibWorm searches and feeds.
If you just want to catch all posts about CIL2007:
LibWorm search: +(CIL2007 “computers in libraries”)
Feed for this search
But what if you only want to see mentions of gaming at CIL2007?
LibWorm Search: +(CIL2007 “computers in libraries”) +gaming
Feed for this search
(Be sure to check out the videos)
You get the idea. Have fun!
As a part of the 5 Weeks to a Social Library course, Melissa L. Rethlefsen prepared this great screencast to demonstrate some of the nifty things one can do with RSS for a Library’s Web site.

Melissa is the Education Technology Librarian at the Learning Resource Center of the Mayo Clinic College of Medicine in my home town, Rochester, MN.
Melissa’s related syndication resources and tools page
Nicely done, Melissa!
We’ll start with the radio buttons, then move on to search operators that LibWorm understands.
There are three radio buttons beneath LibWorm’s search field, any words, all words, and exact phrase.
any words
By default, any words is selected when you first load the main page of LibWorm in your web browser. Having this radio button selected tells LibWorm that your search results must contain at least one of the words you’re searching for. With the search below, you’re telling LibWorm you’d like to see results that contain either OPAC or sucks.

all words
The all words radio button tells LibWorm that you only want results that contain all of the words you’re searching for. Wth the search below, you’re telling LibWorm that you’d like to see results that contain both OPAC and sucks, but not necessarily in that order or near each other.

exact phrase
The exact phrase radio button tells LibWorm that you only want to see search results that contain exactly the characters in the exact sequence you typed into the search field. With the search below, you’re telling LibWorm that you only want to see posts that contain exactly “OPAC sucks”. Posts that don’t contain EXACTLY this string of characters in this sequence, even if they contain something very similar (like “OPACs suck”) will not appear in the results of this search.

Note: For best results, select the any words radio button before using these operators.
” “
A phrase that is enclosed within double quote (” “) characters matches only rows that contain the phrase exactly as it was typed (see notes on “exact phrase” radio button above).
+
A plus sign before a word indicates to LibWorm that the word must be present in every result returned.
-
The leading minus sign indicates that the word must not appear in any search result returned.
*
The asterisk is the truncation or wildcard character in LibWorm.
Example: suck*
The set of results returned by this query will include items containing words like suck, sucks, sucked, sucker, sucking or “sucktastic.” Okay, no feed is indexed in LibWorm as having used the word “sucktastic” (…until about an hour after I post this).
( )
Parentheses group words into subexpressions.
Example: +”Meredith Farkas” +(”5 weeks” “Five Weeks”)
This query will produce results that contain the exact phrase “Meredith Farkas” AND either “five weeks” or “5 weeks”.
> <
These help influence the relevance sorting of returned search results. If the > is placed before a word or phrase, its “weight” in the sorting by relevance is increased. The < placed before a word or phrase lessens its “weight.”
Example: +”Walt Crawford” +(>”cites and insights” <”Walt at Random”)
This query will return only results that contain both the exact phrase “Walt Crawford” AND either “Cites and Insights” or “Walt at Random,” but it’ll place those that mention “Cites and Insights” higher in my list of results as ordered by relevance.
~
This operator is sort of like the -, but not as emphatic. A search term with this operator in front of it will not be excluded from results returned, but the term’s presence will not be considered in the sorting of results by relevance. It sort of de-emphasizes the search term without making it a hard, absolute NOT.
Try these operators out and you’ll find you can generate very, very specific results.
Searching by URL
To answer Walt’s questions in the comments below, searching by URL sometimes works and sometimes doesn’t because LibWorm strips out an item’s HTML. Searching by URL will work if the URL was in the text of the item, but not if it was only in the hyperlink. Also note that the source URL is not searchable, but the Source’s name is. More advanced searching (by source, by category, etc.) is on the way.
Do you have a query or feed you’d like to create but can’t get it to work in LibWorm? Want to run a query by us to make sure it is doing what you think it should? If LibWorm isn’t processing your query as expected, we’ll get it fixed. If you just need a pointer or two on how to get what you need, we can help with that, too- just drop me an email (
) so we can help.
Want to demonstrate LibWorm for your colleagues? We’ll be happy to help you get your presentation materials together or answer any questions you might have. If you have web conferencing software that can be applied, we’d be happy to demonstrate LibWorm for your group, too.
Keep the ideas and the questions coming- We love ‘em!
I had to smile a little when I noticed this post at Hedgehog Librarian about RSS information overload.
First, because I noticed it via multiple feeds in my aggregator. I have a few feeds set up to let me know when others post links to my blog, and other feeds that look for mentions of RSS in librarianship blogs- so I noticed it pretty soon after it was posted.
Second, because I’ve been thinking a lot lately about how to advise others on managing a lot of feed subscriptions without being overwhelmed. The Hedgehog Librarian describes feeling overloaded at 56 subscriptions, and I’m certain others feel the same way- but I have about 460 feed subscriptions in my aggregator, and don’t ever feel overwhelmed by them. I noticed previously that several folks have written posts on managing one’s feeds, but I didn’t bother to read them because I wasn’t having any problems. I thought I’d go back, read them now, and provide a round-up of the best tips.
A couple of the posts I link to below go much further, I think, than the average user would want to- so I’ve limited my recommendations to what I think are the easiest and most useful to more casual users, like the Hedgehog Librarian.
1. Bundle feeds into folders by subject or category
Marjolein Hoekstra recommends categorizing feeds by topic or subject. I do exactly that. For instance, I bundle together in a folder all the feeds I subscribe to about Medical Librarianship. Rather than click on each feed, I click on the folder and can review them all simultaneously. This lets me review and prioritize (see below) with greater speed, convenience, and efficiency.
2. Prioritize
When I don’t have time, I don’t check my feeds. If I only have a little time to spare, I’ll check just those feeds that I care a lot about, like those from Medical Librarianship blogs, feeds from the blogs of good friends, or the feeds that let me know if someone has linked to my blog (that’s how I noticed Marjolein blog-tagging me even though I was hardly reading feeds while on my blogging vacation). After hardly reading any feeds for about 3 weeks, I had a lot stacked up. Some I slogged through, the rest I just trashed. Relax. Except for those very few feeds that you prioritize, do you really have to read through each and every item in your aggregator? No way. Skim subject lines the way you skim the Table of Contents in a journal.
3. Let Google Reader make skimming easier
There are two features that make my aggregator of choice, Google Reader, ideal for managing a lot of feeds.
First, Google Reader lets me review the contents of a feed or folder in “List View” so I can skim the items just by title, check out just the items that look promising, then click “Mark all as read” in order to clear the rest.
Second, Google Reader lets me view the feed list by toggling between “list all” and “only list updated,” and mine is permanently set to “only list updated.” If there aren’t new items for me to read, the feeds aren’t visible to clutter up the interface
4. Filter your feeds
Marjolein and John Tropea also recommend using feed filtering to make sure you only see the posts from a feed that relate to a topic you care about. For instance, you might use Feed Digest, FeedShake, or FeedRinse to do this quickly and easily. Check out this post for step-by-step instructions on how to do it. Also, I just linked a few days ago to a good article on feed filtering that is worth reading.
5. Search-based feeds
I subscribe to a lot of feeds created by very specific searches in feed-generating search tools like PubMed and LibWorm. One of the things I like about LibWorm is that it allows me to create feeds out of the entire biblioblogosphere based on a keyword search, tag search, or subject. I’m also in favor of search-based feeds from technorati or del.icio.us, but only if the search is very specific. If the search is too broad, you’ll only add to the feeling of overload.
It’ll get easier!
It will get easier, I promise. RSS is still a very new technology, and aggregators are still pretty simple. Soon, aggregators will be available that will learn what sort of things you value most, and prioritize your feed contents for you, help you generate search-based feeds, and have built-in functions for mashing/filtering feeds.
Since starting work on this post, I’ve learned that the (alias) Hedgehog Librarian is someone I like and am friendly with from a ListServ (which is one of the reasons I’ve linked to her blog multiple times in this post)- so I’ve happily added her feed to my aggregator so I don’t miss anything else she shares…and I know with confidence that I won’t be overwhelmed.
Over at the JMLA Case Studies in Health Sciences Librarianship blog, Rachel lists a bunch of NLM resources for Getting Help With PubMed, for everyone from beginners to experts.
Bookmarked for later reference.
This post is dedicated to David Schad, Opera evangelist.
A reader with the great pseudonym of Per Sivle left a comment earlier today detailing how to add PubMed to the search bar of Opera:
Just to voice the Opera way of adding search engines:
Right-click in the search field in PubMed and select “Create search”. You can do this in almost any search-engine. Furthermore, you can assign a nick-name to every search engine you add. As in “pm” for PubMed, for example. To do a quick and dirty search in PubMed, you hit F8 to focus on the address-field in the browser, type “pm diabetes” and hit enter.
As a medical librarian, with the need of multiple lookups in every direction; e-journals, ISSNs, ISBNs, other references etc (you probalby know what I am talking about), I would be lost without my browser. The fewer keystrokes and mouse-moving to get to any given search-engine _results page_, the better.
Since I don’t use Opera, I’m grateful that Per left this comment and I’m pleased to share it- but I cannot myself vouch for its accuracy. YMMV.
Oooh…they make it so easy!
Some users may not know that both IE and Firefox have search bars built into them that are very adaptable. Almost any kind of web search can be added to these, but today we’ll look at adding an essential search tool for medical libraries: PubMed. Once this is added, you can search PubMed no matter what page is loaded in your browser. In other words, you won’t have to “go” to PubMed in order to search PubMed.
Add PubMed search to Firefox 2.0
Using Firefox 2.0, go to any PubMed page…like this one.
Click the drop-down arrow in the search bar

Select Add “PubMed Search”

Ta-da!

To switch back to any other search, just click the drop-down again.
Add PubMed search to Internet Explorer 7
Using Internet Explorer 7, go to any PubMed page…like this one.
From the search bar drop-down, select Add Search Providers > PubMed Search

Click the Add Provider button

Ta-da! Now you can choose PubMed as your engine for the search bar by selecting it from the drop-down.

Yep, you can set up one-click feed subscription from IE7 to BlogLines, too, but you have to install an add-on first. Also, it takes two clicks and doesn’t work for me as advertised by BlogLines.







Restart Internet Explorer 7.
How to use the add-on
Go to a page with a feed, like Tame The Web. Note that the orange feed button on the IE7 toolbar lights up to indicate a feed has been detected:
![]()
Now, according to BlogLines, all you have to do is “…look for the big orange RSS button that appears in your IE 7 toolbar. Click on it and you’re done – you’ve just subscribed to that feed in your Bloglines account.”
It isn’t true. Two clicks are required.
If we click on the orange feed button from Tame The Web, we see TTW’s feed, neatly displayed for in-browser viewing, with this included:

We can subscribe to TTW’s feed in BlogLines by clicking on either of the spots indicated by the red arrows above.
A few thoughts:
Firefox’s one-click subscription in BlogLines actually is one click. IE7 requires two.
Firefox natively supports one-click subscription without any need to install add-ons.
There are other web feed add-ons for IE7 here, and more will likely appear soon.
The large developer community of Firefox enthusiasts will whip up extensions to make Firefox 2.0 support their favorite aggregators (and other online services/tools) pretty quickly. I’m less confident that these will be quickly available for IE7.
Walt Crawford noted in a comment at davidrothman.net:
When I upgraded to FF2, it struck me as trivial to configure it so that a click on the new location-bar orange goodie brings up the Bloglines subscription page.
I felt the same way, but Walt and I are both fairly computer-savvy. Many users (and libraryfolk) don’t have this advantage. Hope Leman wrote:
I use both browsers but don’t know how to use the RSS features and need help. And I am deeply into RSS–imagine how puzzled are the millions of people who don’t know diddly about RSS.
Hope’s not alone, either. Over on Randy Morin’s RSS Blog, a commenter calling himself “Bull” writes:
What a pity that IE7 and FF2.0 developpers do not explain how to make RSS readers compatible with one click subscriptions. I am still looking for any documentation on this topic…
So this post will try to address some of these concerns.
How to configure one-click feed subscription in Firefox 2.0
In Firefox, click on the Tools menu, then Options

In the Options window, click on Feeds, select the radio button for Subscribe to the feed using:, select BlogLines, Google Reader, or My Yahoo (I chose BlogLines), and click the OK button.

How to USE the one-click feed subscription
As an example, we’ll visit the Librarian in Black. Notice that in the address bar next her site’s URL is the square, orange Feed icon.

All we have to do is click this icon, and I’m at a BlogLines subscription page for the feed at Librarian in Black.

Easy and convenient.
How to add support for another web-based aggregator in FireFox 2.0
Bull’s concern was on how to make aggregators compliant with one-click subscription. It seems that a Firefox extension might need to be built for each in order to make this work properly:
This can also be done programmatically by an extension, which is done by setting the value of the browser.feeds.handlers.application option to the pathname of the application to use for reading feeds.
Got that? Great.
Much more here on how to add support for an aggregator in Firefox 2.0.
So it looks like providers (or savvy users) of online feed services need to build and offer extensions for Firefox. Here’s hoping they all do it soon.
On behalf of Hope Leman, a huge fan of R-mail, a note to Randy Morin: You gotta’ build a Firefox extension that users can quickly and easily install to make these changes to make one-click subscription via R-mail a convenient reality. It would make Hope’s day. Please?
