Thank you. --angelina The DCM Z1 in PDF format is available on the PCC Web site NACO page specifically at: http://www.loc.gov/catdir/pcc/naco/z1.pdf More specifically the page you need for citing Internet resources begins on p. 81 with an example oon p. 82.

I am not successful all the time in using the Catalogers' desktop. Today I cannot log into it at all. Anita is not there today to help me. I would like to know if I should print out the copies of BFM, Z1, etc., but since they area being updated constantly paper records may not be a good ides. What is BFM? I don't even know what it is. I am trying to see the $u in the 670 field for referring to an Internet resource. The examples in p.59 is not that helpful. Thanks David. --angelina Angelina Joseph Cataloging Librarian Law Library Marquette University Milwaukee, WI 53201 Ph: 414-288-5553 Fax: 414-288-5914
