I think I’ve mentioned it before - but if you find yourself having to read lots of .pdfs on screen, and you want to mark them up in some way, but can’t afford a full version of Adobe Acrobat, can I utterly recommend Skim - which is free: a .pdf reader which lets you highlight text, add notes, arrows, diagrams etc . I’ve been using it for a while, but the most recent version (1.1.2) is infinitely more intuitive than before. Well worth checking out….

To be combined with Yep for complete .pdf nirvana.
