Although CTS is primarily intended as a service to other computer programs, this site includes simple XSLT transformations to display the server's reponses as HTML. You can browse a small selection of texts including canonically cited literary and technical documents, and illustrating different writing systems and directions of writing. You can use CTS URNs to work with different versions of a work, and with citations of a work at different levels of its reference hierarchy.
Specific examples illustrating the CTS protocol, with live links to requests.
