Foder's guides have long been considered the travelers' Bible. Well-researched, up-to-date, and complete, they provide just about anything you need to know when traveling. There are country guides, regional guides and city guides but a guide such as this one gives an overview that will help you plan your trip in advance.
This guide to Europe includes 31 European countries as of 1995. That is what the cover states but the table of contents only lists 29. Each country is divided into regions and major cities or tourist areas within the region. It includes maps, hours of opening, admissions (these will not be current), restaurants, accomodations and more.
This book is primarily recommended for research. If you are trying to determine which places are do-able within your time frame this will be of great help.
