I wrote a blog early in 2012, noting the fact that the Cambridge Structural Database (CSD) had grown to include over 600,000 entries. CSD users that visit our online portal to the CSD (known as WebCSD) will see that the latest update (released on 25th March) pushes the size of the CSD to over 700,000 entries.
What users may not be aware of is that the CSD has actually held over 700,000 entries since December 2013, but in a way that’s a bit harder to spot. WebCSD is frequently updated to include the additional crystal data as it reaches us here in Cambridge. The last update of 2013 brought the total number of structures in the CSD to over 687,000. Not a particularly round number you may think. However, the update also included the most recently published data available to the CCDC - over 19,000 structures - which we make available alongside the CSD as CSD X-Press. That brought the total number of structures available to CSD users to over 700,000!
