Neural Networks: Algorithms, Applications, and Programming Techniques (Computation and Neural Systems Series) by Freeman, James A., Skapura, David M. (1991) Hardcover
If you need to learn neural networks, and you do not know anything about them, this is the first book you should read. If you cannot get this book, then Neural Networks and Deep Learning is a free good second choice.
I like this book, though, because it focuses on various aspects which were seen as critical in the early '90s...and how they tried to tackle it by resorting to neuroscience. The only problem I have is the code given is in Pascal.
