PDF Booklets - Information

How to tell if you have the latest edition of a booklet

The edition number of a booklet is denoted by the last digit of the booklet’s number so, for example, PDF-001-1 is a first edition but PDF-001-2 is a second edition. A new edition number is only allocated where there is a substantial update of information, such as a complete re-write or the addition of more information or photographs. A suffix is added, for example PDF-001-1a where there is a revision of a booklet with, for example, a  text amendment or the addition or correction of a photo credit or maybe the addition of a single photograph where the body of the book is not substantially changed. In this way you can always check if you have the most up-to-date edition in your library.
