Schaum's Outlines are a series of supplementary texts for high school, AP, and college-level courses. The full name of each outline is Schaum's Outline of Theory and Practice of the outline's subject, but this is almost always shortened to Schaum's Outlines. The outlines cover a wide variety of academic subjects. The series originally featured titles in mathematics and engineering, but has branched out into computer science, biology, and other fields.
