The GenBank sequence database continues to expand its data coverage, q
uality control, annotation content and retrieval services. GenBank is
comprised of DNA sequences submitted directly by authors as well as se
quences from the other major public databases. An integrated retrieval
system, known as Entrez, contains data from GenBank and from the majo
r protein sequence and structural databases, as well as related MEDLIN
E abstracts. Users may access GenBank over the Internet through the Wo
rld Wide Web and through special client-server programs for text and s
equence similarity searching. FTP, CD-ROM and e-mail servers are alter
nate means of access.
