A copy of the version of Jonathan Bowen's page “Logic Programming” from December 5, 2000, was previously at the present address (the original page has been at http://archive.comlab.ox.ac.uk/logic-prog.html in the past). You may find this copy now by clicking here.

Copies of some further versions of Bowen's page can be found at Internet Archive (the last one is from August 2, 2005). Much newer resources with information on Prolog are available on the Internet, for instance the Prolog Resource page at http://wiht.link/prolog_resources.
