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):
