How do you determine the date of an antique map/book/print?

Many antique maps/books/prints include the date of publication, either in the title or where publication information is included. These dates often refer to the first year the book, map or print was offered for sale or the year the right to print the book, map or print was obtained. Such dates are not entirely reliable. Many books, maps and prints were issued for more than one year without changes. For these items, we need to look at the content of the item or other clues for more accurate dating. The dates we list are usually accurate to within 10 years. We make best efforts to use our available reference tools to accurately date each item we offer for sale. If you have concerns, please don't hesitate to ask.
