Record only the year; do not give months or days. If both first and last issues are in hand, give the year of the first issue followed by the year of the last issue (AACR2 12.4F1/12.4F2). If both first and last issues are published in the same year, give the year only once. Precede a copyright date with a small "c." Give the year in brackets when it is supplied (i.e., no separate publication date appears in the piece). When supplying a date, give the complete year; do not use approximate dates such as "[198-]". If you are uncertain about the probable date, add a question mark. Example:
