When I first joined the CCDC almost five years ago the CSD had just passed the 420,000 mark. The half millionth structural determination was included in late November 2009, and the 600,000 milestone was reached just last month: a little over two years later. The growth of the CSD since 1972 is recorded on the website, and shows a continual and ever-increasing rate of growth. This rate of increase has actually been used by researchers to show the development of specific areas of study, I recently attended a talk where it was shown the number of metal-organic frameworks (MOFs) deposited in the CSD was doubling at approximately twice the rate of the CSD as a whole.
