Buying books A good book for a library, speaking of the book as to its wearing qualities and as to the comfort of its users, is printed on paper which is thin and pliable, but tough and opaque.

Its type is not necessarily large, but is clear-cut and uniform, and set forth with ink that is black, not muddy.

It is well bound, the book opening easily at any point.

The threads in the back are strong and generously put in.

The strings or tapes onto which it is sewn are stout, and are laced into the inside edges of the covers, or are strong enough to admit of a secure fastening with paste and paper.
