Books online for free from the NIH
Within the PubMed architecture, there are a lot of resources, visible on the pulldown list next to the search field. If you browse down a bit, you’ll see “Books”. (direct link)
These are HTML-formatted versions of textbooks, conference reports, and other items of scientific literature outside the realm of journal articles. Unlike university journal subscriptions, they’re available anywhere like PubMed itself.
Some example items of note:
In Vivo Optical Imaging of Brain Function, 2nd edition Ron D Frostig, ed.
Electrochemical Methods for Neuroscience Adrian C Michael and Laura M Borland, eds.
Methods for Neural Ensemble Recordings, 2nd edition Miguel AL Nicolelis, ed.
BTW, did you know that the NCBI software framework is online and documented? The API for BLAST, database interfaces for PubMed, etc. You can interface your own code will all of the resources at NCBI. Nice. (link)
