Virgil database for rich links (1999 update).

With so many databases available for research in the Human Genome Project, it is crucial to efficiently relate information from different resources. For that purpose, we maintain Virgil, a database of rich links for data browsing, data analysis and database interconnection. Virgil current version contains more than 40 000 rich links from five major databases: SWISS-PROT, GenBank, PDB, GDB and OMIM. Materials described in this paper are available from http://www.infobiogen.fr/services/virgil/
