In one of Bill's weekly postings (Link) he mentioned Adolix Split And Merge PDF. I'm posting to recommend it. This app fills something that I have found to be a recurring need, the ability to split and merge items into PDF files. It works like a charm and its free. The only down side is that the free version doesn't allow you to merge images or Word files in, you first have to convert your files into PDF format (you can use PDFCreator for that). Download Adolix here.
