Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.

I got this item within a few days of my purchase. It is exactly what I wanted -- I look a whole size smaller, instantly. I tried on the Squeem in a boutique and fell in love, but they were asking almost $200 for it! I highly recommend this item and the seller.

This is not a book, its a pamphlet that gives a very terse overview of the PL/I language. Its not a beginners book but a primer for experienced programmers. The only current book on PL/I is "The New PL/I" by Eberhard Sturm which is already out of print after being out less than 2 years
