I've just received the 2004 eds of  "Four-year colleges" (formerly
"Peterson's 4 year colleges") and "Two-year colleges" (formerly
"Peterson's 2 year colleges") and I cannot really understand why there
are new lc / nsdp records for these titles. Is there some reason why the
drop in corporate name here did not qualify as a minor change?

OCLC records are:
    OLD RECORD "Peterson's ... 4 year colleges" (OCLC #39401312)
    NEW RECORD "4-year colleges" (OCLC #47250455)

    OLD RECORD "Peterson's 2 year colleges" (OCLC #39738124)
    NEW RECORD "2 year colleges" (OCLC #47942507)

Thanks,

Chris
