The Association of Greek Academic Libraries (HEALink) now provides access to the Cambridge Structural Database (CSD). CSD is a comprehensive repository of identified and curated organic and metallo-organic crystal structures of micromolecules.
The search is available in the website https://www.ccdc.cam.ac.uk/structures/, through the IPs of the University of Ioannina.
There is also the possibility of installing the base locally through a client in a windows environment for a limited number of licenses. For more information and to receive an activation key, you can contact Mr. Zisi Simaioforidis of SEAB at zsimaiof[at]heal-link.gr.
