I am trying to export my blog http://costlyheaven.blogspot.com to a nice pdf document that can be edited and printed in book format. Is it possible with any of the adobe or third party products. Please suggest.
I have no idea what you mean by export. That depends on what software you are using. You can always print to the Adobe PDF printer. However, editing is not something that you really want to do for a PDF. PDFs were meant to be final products and the editing capabilities are limited and were meant only for minor changes. In printing the blog link you gave, each page printed as a graphic that further limits your ability to edit. Why not just download the HTML and edit that?
