I am considering taking my articles that have been published so far and making them into a nice one-volume book (paperback) that I can send with job applications. The problem is, self-publishing websites like lulu.com require (I think) that your uploaded book be one pdf file. I don’t have a very sophisticated pdf editor (foxit), so how do I do it? I found a great site called pdfhammer.com which is free. Check it out!
