Thanks for the references to latest entry articles.

 Didn't the note that kicked this discussion off mention something about
 Northwestern studying EARLIEST entry? (I prematurely erased the note).
 If something recent has been written about that, it might prove an
 interesting read.  If one has the right online integrated system, one
 never change a 245 again, just add more indexable title fields with new
 title changes--if one has subscribed to the latest entry method and
 philosophy.  It could be programmed if a patron puts in one of the
 title, the bibliographic record comes up showing all the titles clearly--
 maybe in the form "1st title [245]/2nd title [246 redefined?]/3rd incarnation/
 etc."?   It sure would make recon easier!  New records would continue to be
 made for changes in responsiblity.

 Obviously I'm someone uninformed and naive? I'm a little too lazy to walk
 over to our General Library to search the literature.
