The Molecular Biology Database Collection: 2004 update
Michael Y. Galperin

The collection includes databases previously described in NAR, but not represented by full articles in this issue, as well as selected other databases that are relevant to biologists. Hot-links are provided to all of the databases included in the compilation, as well as brief summaries of the content of each database.

The category and database order generally follows that in the compilation paper. However, many databases appear in more than one category.
