The Illustrated Encyclopedia of Stamps & Coins by Dr. James A. Mackay is a comprehensive visual reference for collectors of postage stamps and coins from around the world. The 2013 Hermes House edition presents information on more than 6,000 stamps and coins, together with practical guidance for beginning and developing a collection.

The book is particularly useful as a general collecting and identification reference, combining historical information with illustrations and advice on building, organizing and caring for a collection.
