Combinatorics is a relatively recent development in mathematics, one which is generally easy to explain, but with many difficult open questions. Van Lint and Wilson do an excellent job explaining, but there are a few places where the reader needs to know some background to place the particular problem in the appropriate mathematical context. Understandably, if the authors were to include all the mathematical machinery needed, the book would be huge! Instead, they have chosen to describe as many facets of the field as possible, and therefore have written a broad, well-balanced book which approaches the topic in a non-threatening way.
