In a recent comment, Creaky (Kathleen Crea) made me aware of LigerCat, a 3rd-Party PubMed/MEDLINE tool that is new to me. I’m really enjoying working with it.
I’m sure that more experienced Medical Libraryfolk don’t have to do this, but as I start putting together a lit search, I often start by going to the MeSH Browser http://www.nlm.nih.gov/mesh/MBrowser.html to begin working out what MeSH terms I might be working with. Alternately, I might go to Novo|Seek or GoPubMed with a few key words to get a frequency analysis of MeSH terms. In these examples, I’m doing some preliminary searching on Acute Disseminated Encephalomyelitis.
LigerCat isn’t necessarily *better* at this, but its presentation is simpler. Rather than putting the frequency analysis of MeSH terms in a left sidebar, it gives a cloud of MeSH terms:
Seeing the biggest, most obvious tag item in the cloud (see above) is delightful. If one clicks on the tags in the MeSH cloud, they’re added to the search. When you’re done adding terms, you can click “Go to PubMed” to run the search there.
In this example, the query run in PubMed is:
(“encephalomyelitis, acute disseminated”[MeSH Terms] OR (“encephalomyelitis”[All Fields] AND “acute”[All Fields] AND “disseminated”[All Fields]) OR “acute disseminated encephalomyelitis”[All Fields] OR (“acute”[All Fields] AND “disseminated”[All Fields] AND “encephalomyelitis”[All Fields])) AND (“Encephalomyelitis, Acute Disseminated”[mh] AND “Humans”[mh] AND “Treatment Outcome”[mh])
…and the results aren’t bad.
If I was caught up in Google Reader (I’m not, and haven’t been for about 15 months), I would have noticed Creaky’s post on LigerCat a couple of days ago. This reminds me to move Kathleen’s feed into my “High Priorities” folder. You may want to do the same.
