Since the first structure was released on June 20, 2002, the number of sructures has increased steadily.

Year# of structures
2002 10

The submission rate is increasingly similarly and has now reached nearly 100 structures per year, distributed over about 150 EMDB entries.

The EMDB Atlas pages register about 300-400 visits every month, with between 1000 and 1500 structures being viewed. The number of visits increased by about 20% from 2007 to 2008.
