CONSER catalogers generally prefer a source with the most complete presentation of the numbering (any sequence of sequence of numerals, letters, and/or dates) provided it appears prominently or is stated formally. “Most complete” does not necessarily mean that the components of the numbering are spelled out, only that they are present. (CCM:8.3.1b) Completeness is desirable because it simplifies the (588) Description based on note.
As every serialist knows, completeness is not always available.When the serial has both a numeric and a chronological designation, each part of the designation may be taken from different sources. Each part of the numbering is selected as a separate entity and then joined with the appropriate punctuation. (Piecing together different sources. The numeric designation may be pieced together from various sources when it is clear that the publisher intended both parts to constitute the numeric designation. When this is not clear, do not piece together the numeric designation from more than one source. (CCM:8.3.1d)
Volume 1" appears on the cover and "issue 1" appears on the editorial page. Is "issue 1" another way of saying "volume 1" or is it a part of the volume (i.e., vol. 1, issue 1)? If a later issue is also in hand showing volume 1, issue 2, then the publisher's intent is clear and both may be transcribed as the numeric designation. (ex. CCM:8.3.1c1d)
The lack of completeness in source of numbering information sometimes complicates the source identified in the Description based on not.
Cover (Source of title proper) has: November/December 2013; table of contents has: Volume 4, Number 6 (November/December 2013)
Record 588 as:
588 0# Vol. 4, no. 6 (November/December 2013); title from cover.
When to take the numbering from another source not prominent or a statement that is not formal. CONSER practice is to record a designation from an informal statement, such as a statement found in the preface, if there is no other number or date that can serve as a designation and the publication is definitely a serial. If the choice is between type of date versus prominence, in most cases, prefer prominence. Prefer a coverage date found in the preface, however, to a copyright date.
