PDF is a right PITA; this road-block to accessing and reviewing research papers comes up time and again. It would be most useful if anyone can recommend a free solution for accessing text from PDF files - or alternatively, I think the paid-for version of Acrobat Reader has that function so people with access to that software could rip the text from PDFs as a service to the rest of us. Maybe I'll look into it one day soon...but if anybody has a neat solution for us, do shout up...
I just tried copying and pasting the text to a text editor using the Gnome document viewer running on Ubuntu Linux and it worked fine.
