In the first quarter of 2003, approximately 1,200 structures were deposited to the PDB. 76% of all of the structures received during this period were deposited with a "hold until publication" release status; 9% were deposited with a specific hold date; and 15% were deposited with a "release immediately" status. 85% were the result of X-ray crystallographic experiments; 11% from NMR.
