PDFClerk is your personal assistant for PDF Documents.
In its current incarnation it allows you, among other things, to join multiple PDF documents together, rearrange the page order, delete individual pages, impose multiple pages onto a sheet of paper and rotate pages on imposed sheets, making it easy to create your own books, booklets and magazines.
You can even create books for languages that read from right to left like Arabic, Chinese and Hebrew.
