The Fingerprint is an identification system for ancient editions used in librarian context.

It consists of four groups of two pairs of symbols taken from the last and penultimate lines of four specified pages, one pair of symbols per line, taken from each bibliographical unit.

es.: i-me e.ue i.i, Eisa (3) 1557 (R)

The use of fingerprint is largely diffused all over Europe, particularly in Italy. Its use is of fundamental help in authomatized collective cataloguing. In EDIT16 it has a great important role for the identification of editions, issues and variants.

The Fingerprint rules are officially edited in 1984 in a trilingual version (English, French, Italian).
