Chemistry now has site-wide access to WebCSD.  Although there is reduced functionality compared to the full, installed version, it has some significant advantages, primarily that it gives access to “CSD X-Press” which are the most recently recieved structures.  As these have not been fully processed by a CCDC editor yet it is likely that some of these will contain errors and some of the entries won’t contain fields that are added during the curation process, such as ‘recrystallisation solvent’ and ‘bioactivity’, however, they are much more current, making literature searches much more reliable.

Access is from http://webcsd.ccdc.cam.ac.uk/
