This example shows a single volume item with an accompanying sound cassette, each with an individual barcode and housed in a separate subcollection. Since each item has a different call number, no identifying label is necessary.
The union of words and music in medieval poetry / edited by Rebecca A. Baltzer, Thomas Cable, and James I. Wimsatt. -- 1st ed. -- Austin : University of Texas Press, 1991. vii, 157 p. : ill., music ; 24 cm. + 1 sound cassette (ca. 65 min. : analog) L.C. CALL NO: ML172.U54 1991

NOTE: Ordinarily we would not use a CCAL for this main item since the a is STACKS and the b repeats the CALL without additional information. However, in this case we use both CCAL a and b for the main item since our practice is to use a CCAL for all items in a library whenever it is needed for any item in that library.
NOTE: You must include a space after the subcollection and before the b in CCAL so that the subcollection and call number display properly on the RLIN PAR screen. Without a space they run together. However, if the space is placed after the b rather than before it, some IRIS programs will sort the call number incorrectly in those reports.
