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 Work Access ).
For integrating resources with titles that change, revise the title to reflect the current iteration. Make notes, using date spans, to indicate earlier titles.
For expressions of serial works with titles that change over time, identify the expression using the latest title this particular expression has held. If the title includes a date, name, number, etc. that varies from issue to issue, omit the date, name, number, etc., and replace it by the mark of omission, unless it occurs at the beginning of the title, in which case, do not record the mark of omission.
If the title of a serial or integrating work is presented as both an acronym title and in spelled out form, choose the spelled out form as the title regardless of how the two titles are presented typographically.
Title transcription can sometimes be an art and should be left to the judgment of an experienced cataloger.
