Haven't publishers just made catalog maintenance a joy! I recently noticed one record for a loose-leaf publication, now issued by a publisher to be left unnamed, that had changed publisher statements three times in the last year. Until 1997, "Imprint varies" was not a note that I'd ever considered using on a loose-leaf publication.

The Bender binder replacement project is coming to a close, but have you finished all your bibliographic maintenance associated with that publisher's decision? I lost track of how many new binders came with new edition statements, but of course, they weren't always complete new editions. Notes had to be added such as "Updated to 3rd ed. , 1997." But perhaps my favorite change had to do with what was no longer there: series statements. Several Bender titles that were originally issued in a numbered series "lost" the series on the new binders and title pages. What does one do about the missing series? At LACLL we had originally thought we'd use the technique that appears on Practising Law Institute series when the serial program handbooks jump series:

   490 1  1983-1996: Title of series
   490 1  1997-   : Title of series
   830  0  Title of series.
   830  0  Title of series.

How would the Library of Congress deal with this problem? Judy Kuhagen of LC's Cataloging Policy and Support Office replied via email:

A couple of the forms for the 500 note that she suggested included:

   500     Series on t.p. from 1988-1994: Title of series.
   500     On series t.p., 1990-1995: Title of series.

At LACLL we used one of the suggested notes on Franchising by Gladys Glickman, LC 76010835.

   500     Series on t.p. from 1969 to Mar. 1997: Business
           organizations ; v. 15, 15A-15C.
   830 _0  Business organizations ; $v v. 15, 15A-15C.

You can now take a look at other loose-leaf records like the above example on the Los Angeles County Law Library Web opac at <http://lalaw.lib.ca.us> A keyword search of "series on t.p." will get you quite a few other examples to consider.
