The Alex Manager includes a rudimentary HTTP client. It automatically extracts descriptive information from the documents like titles, dates, MIME types, remote locations, and lengths. Selections are made from the menus and the remote documents are archived locally, indexed with freewais-sf, and finally described via a template added to the Catalogue. The Alex Manager is also responsible for creating the browsable author and title lists supplimenting the Catalogue's searchability. Without the Alex Manager, I would not have had the patience to create the Catalogue nor the time to persue its maintenance.
Access control is used to insure data integrity from malicious users.
An NCSA HTTP server is used to facilitate access to the Catalogu for those who want it. These are the usual suspects in just about any Web-based information system. While the hardware and software support the Catalogue, the Catalogue is ruled by its collection management policies. These policies govern the purpose of Catalogue and what it contains. They embody the fundamental principles of librarianship.
