Marc Tapes in Trinity College Library

The Library is now in a position to check the receipt of copyright accessions by matching incoming publications with the bibliographic data on the British Marc tapes, distributed by the BNB. The Copyright Agency can be notified of material which has not been received or perhaps not even been claimed by the Agency; claims must be submitted to publishers within 12 months of publication date. It is possible to establish both for the Library and for readers within the subject fields prescribed by them, what current British copyright material has been received each week, before it is catalogued. When American Marc tapes, also to be distributed by BNB, covering North American and a wide selection of new European publications become available to the Library for book selection and ordering, (= phase 2), readers will receive a second listing of SDI. This second listing is, in fact, a current awareness service of new published books and does not correspond to the Library's accessions. The Library is now introducing catalogue worksheets for the production of machine readable records of secondhand and noncopyright material acquired by the Library, as well as ‘BNB exclusion’, i.e., anything not on BNB Marc tapes. Once the records have been fed into the system from the catalogue worksheets, readers may receive accession lists of all books received in the Library and included in the classified catalogue on the subjects they have specified for their SDI profile.
