Thanks to Matt White, M. Ed. student for this tip:
“Converting from pdf to word documents is possible but requires a specific program in order to do it. It is actually pretty neat how it works as I was able to use the program to convert a 240 page pdf document directly into a word one. Zamzar is the online program I used.” (Note that UWO email sees the sender as spam so it may end up in your spamtrap.)
To Merge multiple PDF documents, try mergepdf.net (Thanks to Jacqui Specht for this tip.)
To create a pdf from a Word file (and most other Microsoft applications), try PrimoPDF.
