There are three goals in submitting electronic manuscripts. For more information see our Guide to Electronic Document Preparation and Submission . If a job is being permanent bound, the pages are perforated so that glue can go through the small cuts and attach the pages to the cover.
Permanent binding is used with jobs that have a squared spine.
If a job is being saddle-stitched, the pages are folded so that the middle pages fit inside the outside pages of the book. When all pages are assembled, the pages are stapled. Saddle binding is used for publications with fewer pages that do not require a spine. It should have clearly marked crop marks on it that represent the trim size of the book. ISSN stands for International Standard Serial Numbering.
