Hello.  I am in the process of creating holdings for older bound and
microfilm volumes that are in my library.  We have bound volumes of
Atlantic and Atlantic Monthly.  The Worldcat record # 1580813 for the
Atlantic says the range of years it was published was 1932-1971.  But I
have the physical volumes from 1932-1948 that actually have the title
Atlantic Monthly.   I also have bound and microfilm from 1949-1971 that
have the title Atlantic.  Is this one of the cataloging rules about
where the title did not change significantly, so they did not create a
new record?
