4.2.1.2 Choice of title

If several different titles appear in the work, choose the one that appears most prominently. If no title appears prominently, but one is taken from somewhere in the item, note the source of that title. Variant titles not used should be recorded as title variants (see 1.3). For serial titles with minor changes in title and/or changes in subtitles, revise the title to reflect the current iteration. Make notes, using date spans, to indicate earlier titles. Title transcription can sometimes be an art and should be left to the judgment of an experienced cataloger.
