I recently picked up a copy of this classic, and I wish I had not waited so long to get it. Everyone always speaks highly of it. It contains 500 games from the 19th and early 20th century. It is organized by opening system, with the games presented chronologically within an opening.
The annotations are pretty brief, but it seems like a good book for brushing up on early chess culture and working through a bunch of games at a brisk clip. I have just started to work through the book, and have been using it to work on playing through a game blindfold although I am using the crutch of staring at a blank board while I do it.
If you have not bought the book because of descriptive notation I would highly recommend you take the time to learn descriptive, and you will be greatly rewarded by this book and the many others in Dover's library.
Here is a game I played through tonight that contains a pretty finish. I was happy that I saw 27..Ng4+ while playing through it blind.
