from Openbook-l: "By popular request, we have posted on our website a new OpenBook
Technical Beta Preview release. This release includes: MARC21 bibliographic, authority, community, classification and holdings format, as well as a major circulation component and a rudimentary Z39.50 client in the OPAC as well as in the
cataloging interface. (Z39.50 can be best described as early beta!)... If you want to get some experience with the interface and the system, please visit demo.trfoundation.org/opac/ since it runs the most up-to-date build of our current system at all times."
