246 Publication Statement

The source of information would preferably be from the same source as the title, but if it is not there it may be taken from the disc label, accompanying material, or container (RDA 2.2.4)

Transcribe places of publication and publishers' names in the form in which they appear on the source of information (RDA You may transcribe it exactly as it appears, including capitalization and punctuation or apply Appendix A (old AACR2 capitalization), whichever is easier (YUL decision). However, do not abbreviate anything which is not abbreviated on the piece. When place of publication isn't on the source, supply the place of publication if it can be ascertained from other sources. Avoid using "Place of publication not identified" if it is possible.

If there is more than one publisher, record the first place and publisher (RDA 2.8.2).
