Adobe Acrobat is my friend. I have the book titles that you reference, and then some, but I still feel drawn to the shorter texts (thesis papers, RAND studies, etc.) posted in the reference library on .pdf. I can digest several topics in a weekend and gain a wider grasp of discussion points that way.

Granted, they tend to be very topical, but most of the good ones reference core material and points made in the classic texts anyway, so I tend to get a dose of what those arguments are without having to grind through several hundred pages of the same points, just varied at times by the vignette chosen. Your mileage will certainly vary, but have you printed out a few of those and dived into them?
