[DCRM-L] RBMS PS review Q4: Extent of text

[Mascaro, Michelle]

I would like to resume discussions of areas where the draft RBMS Policy Statements significantly differs from RDA or DCRM.  The next topic of discussion is extent, specifically extent of text.

Recording unnumbered pages or leaves

For extent of text, the draft policy statement differ from RDA and specify to bracket sequences of the unnumbered pages/leaves (as we did in DCRM and AACR2) versus spelling out unnumbered pages/leaves (as specified in RDA).  (E.g., [8], 260, [2] pages, NOT 8 unnumbered pages, 260 pages, 2 unnumbered pages). The RBMS PS do specify to follow RDA and not abbreviate "pages."  This is also the rare materials approach that is currently followed in the BIBCO Standard Record (BSR).   The rationale for differing from RDA is that rare print materials often have complicated pagination/foliation, and since it is important to record every page/leaf in the item, extent statements can get too unwieldly following RDA conventions.

Recording full sequences of pagination/foliation in a note when pagination/foliation is particularly complex

The RBMS PS (like DCRM(B)) specify that catalogers should generally record full pagination sequences and not employ one of RDA's methods for summarizing complicated pagination (e.g., 1024 pages in various pagings).  One change that the RBMS PS have made from DCRM(B) is if you are electing to summarize complicated pagination/foliation sequences in the extent statement, the option to record the full pagination/foliation sequences in a note has been eliminated (see DCRM(B) 5B6.6 and RDA 3.5.5.8).  The rationale for this change is that with RDA's granular structure, we want sequences of pagination/foliation to be consistently recorded in the extent element and not some times in a note.  For the same reasons, the RBMS PS dropped the option for recording the individual volume pagination of multi-volume sets without continuous pagination in a note (see DCRM(B) 5B18 and RDA 3.4.5.18).  RDA proper has an optional additional that pagination of individual volumes may be recorded in parenthesis after the number of volumes in the extent element (e.g., 3 volumes (xx, 202; xx, 203-514; xxi, [1], 515-800 pages), and there is currently no RBMS PS either encouraging or discouraging the application of this option, leaving the decision up to cataloger's judgment.  There was some question among the examples editors whether a PS should be added saying to generally record the pagination of individual volumes, and I am interested in further community feedback.

Please respond to the list with your thoughts.  For further context a draft of the full RBMS PS to RDA 3.4.5 is attached.  (Nota bene! The examples in this section are still being polished.)  In two weeks, I plan to post a couple new questions related to recording the extents of plates.

Best,
