The worst thing I can say about BioMed Search is that it has an iffy name. The name doesn’t capture attention or memory and doesn’t indicate that it is a search engine for IMAGES. That nit-pick aside, it’s pretty neat.
Built by Alex Ksikes (a Ph. D. student at the University of Cambridge), BioMed Search’s goal is to “organize figures, images or schema found in biomedical articles.”
It has indexed over 1 million images.
