   Well (said with some hesitancy) yes. It depends on a number of issues --   
   primarily what platform you're using and what device. EPub doesn't play this   
   game at all. PDF can be easily annotated if you use either the full Adobe   
   Acrobat program (expensive) or one of the free clones such as Foxfire PDF   
   reader. Kindle also allows for marking up the text, but it's not quite as   
   friendly for sharing that mark up.   
      
   Foxfire PDF is for Windows, btw, so you have to position the cursor with a   
   mouse, then type. Not a big deal. On an iPad (probably on other tablets but   
   I've no personal experience) you can actually write on the PDF with a stylus,   
   dependng on which program you use (I like PDF Expert, personally).   
      
      
   Cheers... Dallas
