The Logic of Provability
"The book contains an excellent combination of values: noble subject, fresh key results, and the gentle, friendly style of the author. It can be recommended as a textbook, as a handbook, or simply as high quality reading in logic."   Sergei N. Artemov, Journal of Symbolic Logic"I found it lively, lucid, and informative...Boolos' style of writing is unusually kind to the reader.  When an argument becomes tricky, he breaks it down into a lot of small steps, showing the reader in detail just how to proceed.  A result is that the book is remarkably easy to read."
