GenBank and WGS Statistics
Notes on GenBank statistics
The following table lists the number of bases and the number of sequence records in each release of GenBank, beginning with Release 3 in 1982. CON-division records are not represented in these statistics: because they are constructed from the non-CON records in the database, their inclusion here would be a form of double-counting. From 1982 to the present, the number of bases in GenBank has doubled approximately every 18 months.
