MAA的Guide系列，就是把一本厚书的内容压缩成小册子，适合强化复习使用。已经出了的有下面9本：
A Guide to Topology
A Guide to Advanced Real Analysis
A Guide to Plane Algebraic Curves
A Guide to Functional Analysis
A Guide to Groups, Rings, and Fields
A Guide to Elementary Number Theory
A Guide to Real Variables
A Guide to Advanced Linear Algebra
A Guide to Complex Variables
不过这套书大多没出几年，电子版不太好找。
