The CCP14 (Collaborative Computational Project No. 14) in Powder and Small Molecule Single Crystal Diffraction was initiated in 1994 to acquire the best and most commonly used programs which are freely available. The software located on the CCP14 site (and its overseas mirrors) is freely available to academic users. General Information about the Collaborative Computational Projects (CCPs): of which the CCP14 is part of the EPSRC Research Computing Initiative "The Collaborative Computational Projects (CCPs), assist universities in developing, maintaining and distributing computer programs and promoting the best computational methods."
