The object of this work is, in the main, to present to mathematicians an account of theorems in combinatory analysis which are of a perfectly general character, and to shew the connexion between them by as far as possible bringing them together as parts of a general doctrine. It may appeal also to others whose reading has not been very extensive.

This textbook is an interactive introduction to combinatorics at the undergraduate level. The major topics in this text are counting problems, proof techniques, recurrence relations and generating functions, and an introduction to graph theory.
by Kenneth P. Bogart - Dartmouth College
This is an introduction to combinatorial mathematics, also known as combinatorics. The book focuses especially but not exclusively on the part of combinatorics that mathematicians refer to as 'counting'. The book consists almost entirely of problems.
