Is there any easy way to do this? Perhaps using Open Office, Photoshop CS2 or a free utility? I've got my dissertation on 3 different files with different headers and footers (originally from OO documents) and i really cant be bothered to fanny about with making templates in OO to let me have them different - but in the same file. So i've got the PDFs.. is there an easy way to merge them into one document so i can upload it for people? Thanks.
