Is the date of publication printed on the item?
The date of publication is sometimes printed on a map or print, more often for older maps, but we do not guarantee this. Items extracted from periodicals often have the exact day of publication printed at the top or bottom of each page; they can often otherwise be closely dated by reference to information on births, marriages, deaths or other news events printed in text elsewhere on the page. Steel engravings sometimes have the year of publication printed below the image. The date of publication of prints or maps is usually derived from the date of publication of the book, atlas or periodical from which the item has been extracted. The date of publication of nearly all titles is stated on the title page.
