I'm seeing a variation and also some questions about adding the dimensions of the CD-ROM. I note in the BL workflow that their policy is not to record dimensions of accompanying material. I did include it, going by 3.1.4 to include details of each carrier type and then applying the LC-PCC PS for 3.5.1.4.4 which says to give inches for discs. Actually I dislike this current practice, maybe now is the time to rethink it (though it's hard to go against LC/PCC practice because it will cause problems then with downloaded records being in inches). I abbreviated the "inches" to "in." because 3.5.1.3 on dimensions points you to appendix B.5.1 and from there to App.B.7 which says that you can abbreviate inches to in. This seems so illogical though, when we've learned that RDA means no more abbreviations. We already have the slightly odd situation of "cm" becuase it's technically not an abbreviation but an SI. Maybe I'm edging towards thinking we either move to metric dimensions for everything or we omit dimensions of accompanying material following BL practice.
