Originally published in 1958, Finite-Dimensional Vector Spaces by Prof. Paul R. Halmos (2nd Edition) is a classic reference book on Linear Algebra, especially if you are looking for an abstract approach to linear algebra.
The purpose of this book is to treat linear transformations on finite-dimensional vector spaces by the methods of more general theories. The idea is to emphasize the simple geometric notions common to many parts of mathematics and its applications, and to do so in a language that gives away the trade secrets and tells the student what is in the back of the minds of people proving theorems about integral equations and Hilbert spaces.
Except for an occasional reference to undergraduate mathematics the book is self-contained and may be read by anyone who is trying to get a feeling for the linear problems usually discussed in courses on matrix theory or "higher" algebra. The algebraic, coordinate-free methods do not lose power and elegance by specialization to a finite number of dimensions, and they are as elementary as the classical coordinatized treatment.
About the author -- Excerpt from the Wikipedia:
Paul Richard Halmos (1916 - 2006) was a Hungarian-Jewish-born American mathematician who made fundamental advances in the areas of mathematical logic, probability theory, statistics, operator theory, ergodic theory, and functional analysis (in particular, Hilbert spaces). He was also recognized as a great mathematical expositor.
