NIOSH/OSHA pocket guide to chemical hazards / editors, Frank W. Mackison, National Institute for Occupational Safety and Health, R. Scott Stricoff, Lawrence J. Partridge, Jr., A.D. Little, Inc. (OCLC #8734681)

This volume has a date of “September 1978” on its title page and a suggestive “78” as part of its publication number, but this printing history on the title page verso:

  Second printing - January 1980
  Third Printing - August 1980
    with minor technical changes
  Fourth Printing - August 1981
    with minor technical changes

but does that merit a new (1981) record in OCLC?

I checked the edition section of their When to Input a New Record document, and was unsure. It may fall under “difference in content”?

Either way, a full and popular record already exists for this printing, with a 1981 date and a note:

500 __ ǂa "Fourth printing, August 1981, with minor technical changes."

This record most precisely matched what I had in hand, so worked well for copy cataloging.


The red atlas : how the Soviet Union secretly mapped the world / John Davies, Alexander J. Kent ; foreword by James Risen. (OCLC #978389095)

This volume has “atlas” in its title, and has quite a few maps in it, but is it really an atlas? Catalogers disagree; OCLC has multiple records for this title, mostly as a book, but one as an atlas.

Our maps cataloger took a closer look, and said that while it had a large section of maps, they were used as illustrations for the text, not the main content of the work themselves. I did feel the maps were numerous enough to merit inclusion in the content type though:

ספר מורה נבוכים /להרב משה בן מימון ; … בהעתקת הרב ר’ שמואל אבן תיבון ; עם ארבעה פירושים … אפודי, שם טוב, ן’ קרשקש, אבברבנאל. (OCLC #29328452)

We found copy possibly matching this book, but without strong skills in Hebrew, and so much omitted (using …) from paragraphs on the title page, how to be sure?

Fortunately, the copy also included a link to an electronic copy online, including the title page, which was an exact match:

The safe care and handling of gases. (OCLC #6526758)

Slides! I’ve never gotten to catalog slides before. It was a nice opportunity to review the rules for this format. The set does have an accompanying audiocassette:

300 ǂa 37 slides : ǂb color ; ǂc 2 x 2 in. + 
    ǂe 1 audiocassette.

So there are two sets of Content/Media/Carrier fields:

336 __ ǂa still image ǂb sti ǂ2 rdacontent
337 __ ǂa projected ǂb g ǂ2 rdamedia
338 __ ǂa slide ǂb gs ǂ2 rdacarrier
336 __ ǂa spoken word ǂb spw ǂ2 rdacontent ǂ3 accompanying material
337 __ ǂa audio ǂb s ǂ2 rdamedia ǂ3 accompanying material
338 __ ǂa audiocassette ǂb ss ǂ2 rdacarrier ǂ3 accompanying material 

However, the soundtrack is considered an integral part of the slide set, so its sound characteristics are included in the slides’ 007 (not as a separate 007):

Chem sources-international–1998 edition. (OCLC #39262429)

This is the thickest book I’ve ever received for cataloging:

300 __ ǂa iv, 2259 pages : ǂb illustrations ; ǂc 29 cm

It made me wonder if RDA had exceptions in the rules for recording Dimensions of a volume related to a book’s thickness (as there are for the cover’s width). There don’t appear to be; it’s probably covered by pagination.
