The rules in AACR2rev that seem to be relevant to this discussion are:

1.2B1.  Transcribe the edition statement as found on the item ... .

1.2C1.  Transcribe a statement of responsibility relating to one or more editions, but not to all editions, of a given work following the edition statement if there is one ... .

1.2C2.  In case of doubt about whether a statement of responsibility applies to all editions or only to some, or if there is no edition statement, give such a statement in the title and statement of responsibility area ... . When describing the first edition, give all statements of responsibility in the title and statement of responsibility area ... .

Examples

NOTE that in the 245, numbers like "rishonah" are spelled out if they are spelled out in the item (i.e. they are "transcribed" as they appear), while in the 250 they are replaced by numerals per App.C.3B1.
