Cambridge Structural Database
We have a campus-wide site license to CSD-Core (formerly known as CSD Enterprise) plus WebCSD. Our current license agreement will expire December 31, 2023.
- Enhanced CSD subsets
- Improvements to SMARTS/SMILES
- Verified database entries increased to 1.16 million
Request activation key and license customer ID
Access to CSD software is limited to current students, faculty, and staff at Stanford. You must have the activation key and the license customer ID before you are able to download the software. Please send a request to the Science Library using your @Stanford email address. Please also include your Stanford ID number in the request.
Use WebCSD or download software
Be sure to remove the old version of CSD before installing the new version. Please note that CSD software must be deleted when users graduate or are no longer affiliated with Stanford.

Established in 1965 by the Cambridge Crystallographic Data Centre (CCDC), the Cambridge Structural Database (CSD) is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over one million entries from x-ray and neutron diffraction analyses, this unique database of accurate 3D structures has become an essential resource to scientists around the world. The June 2015 issue of CCDC's Crystalline Newsletter covers 50 Years of Sharing Crystal Structures (PDF). In addition to coverage of the published literature, CSD searches also contains data published directly through the CSD as CSD Communications that are not available anywhere else.
We have a campus-wide site license for:
- CSD Enterprise includes ALL CSD software and ALL application data
- Partner software (available free to CSD subscribers)
- To aid rescaffolding and fragment-based drug discovery

- By integrating crystal structures into your course you will provide your students with the opportunity to visualise and manipulate real molecules in 3D and to work with experimentally-measured data.
- Information derived from the CSD is vital to structural chemistry research in its broadest sense, and in particular to pharmaceutical drug discovery, materials design, drug development and formulation. More than 2,000 papers and reviews [e.g. 2-4] have been published worldwide that describe research applications using the accumulated data in the CSD.

- CellCheckCSD is a freely available, automated tool for checking unit cells against the CSD during data collection.
- Safely check and edit crystallographic information files (CIFs) without compromising the syntax.
