Currently reading Up the Down Staircase. Written in 1961, it's a "fictitious" take on the NYC public school system as seen though a first-year teacher. It's told in memos, bulletins, notes, letters, etc. This book is as relevant, or even more relevant, today than it was in 1961. The e-book version I have has a forward written by author Bel Kaufman in 2012 (or so). The circumstances around the publishing of the book, her background and her wit make it interesting reading in itself.
