1.4G4. Optional addition.
Apply the option on a case-by-case basis. However, for books always include the date of a later impression, qualified by the word "printing" (without brackets), if the date of the first impression of the edition differs in years. If, after cataloging a later impression, the first impression is received for cataloging, revise the record to convert the date
from the form "[date] ([date] printing)" (e.g., 1970 (1973 printing))
to "[date]" (e.g., 1970),
so that the one bibliographic record can stand for all impressions. If, however, it is an impression other than the first that is received in the second instance, treat this as a copy and do not revise the record.
When applying the rule give both the place of manufacture and the name of the manufacturer even if this means a repetition of data already recorded in the publication, distribution, etc., area.
