Zooming in : the cosmos at high resolution / edited by Regina von Berlepsch. (OCLC #868967245)
My library has no other volumes of this serial, so I chose to catalog this one as a monograph, classified separately, with the series traced. I found two monograph records for this particular volume in OCLC, and the more popular one recorded the title as:
245 00 ǂa Reviews in modern astronomy. ǂn 23, ǂp Zooming in: the cosmos at high resolution / ǂc edited by Regina von Berlepsch.
This is a reasonable approach, as the series title is more prominent than the volume title, even on the title page, but I prefer to use the volume title as the title proper, with the series in a series statement / added entry:
490 1_ ǂa Reviews in modern astronomy ; ‡v 23 830 _0 ǂa Reviews in modern astronomy ; ‡v 23.
Our analyzing, tracing and classifying decisions for this series differ from LC practice, so I edited our local series authority to reflect this.
I expect these two records will eventually be merged, as differing selection of title proper does not justify a new record.
