Many Genbank entries for complete microbial genomes violate the Genbank standard

A survey of Genbank entries for complete microbial genomes reveals that the majority do not conform to the Genbank standard. Typical deviations from the Genbank standard include records with information in incorrect fields, addition of extraneous and confusing information within a field, and omission of useful fields. This situation results from two principal causes: genome centres do not submit Genbank records in the proper form and the Genbank, EMBL and DDBJ staffs do not enforce the database standards that they have defined.
