Bookshelf, the books division of the NLM Literature Archive (LitArch) at the National Center for Biotechnology Information (NCBI), is an online searchable collection of books, reports, databases, and other scholarly literature in biology, medicine, and the life sciences. Bookshelf has a review process for all new content proposals. The book must fall within the scope of core biomedical topics as defined in the NLM Collection Development Manual.
