Transcribe a date of impression or other manufacture as part of this element only if it has not been treated as the date of publication, distribution, etc., following the instructions in 4A6, and only if it applies, or is likely to apply, to all copies of the edition or issue being cataloged.  Such situations will occur only rarely.  Dates of impression or other manufacture associated with a substantially unchanged impression of an edition or issue may be transcribed in a local note, if considered important.

, 1989

Optional local note:  Library's copy: "1990 printing"--T.p. verso

Alternative rule:

If a decision has been made to create a separate bibliographic description for an individual impression, state, binding variant, or copy within a single edition or issue (see introductory section X.1.4 and Appendix E), transcribe a date of impression or other manufacture associated with a substantially unchanged impression as part of the date of manufacture element.  Transcribe the date as it appears, together with any associated words or phrases.

, 1989 (1990 printing)

Note:  Date of impression from t.p. verso

If the date of manufacture appears in the source without an accompanying word or phrase, supply one in square brackets as appropriate.

, 1956 (1959 [impression])

If the date of impression is known from a source outside the publication, supply it in square brackets.

, 1923 ([1924 impression])

If the actual date of impression is known to differ from the date of impression given inside the publication, supply it as a correction within square brackets.

, 1923 (1924 [i.e. 1925] printing)

In the above cases, give the source of the date of impression, if other than the title page, and any explanations in a note.

LC Rare Book Team Guidelines:  Optional (local) note:  Cataloger's judgment.  Alternative rule:  Usually exercise option.  LC will generally catalog at the edition level, but when the decision has been made for an exception, we will exercise this option.
