The Pragmatic Bookshelf | Pragmatic Version Control using CVS
A customer of mine still uses CVS, I would love to own this PDF e-book; I asked them on the forum on that book [Link], whether there is a way to get the e-book [Link]. Update: I got it as a gift from them.
You can find the paper book on Amazon Marketplace as used book and also on eBay for awfully little money.
I really love the recipes in appendix A.2.
