The “Historical Dictionaries of Europe” series is a standby for reference collections. The volumes follow a more or less standard format of several hundred entries with a chronology or two and a selected bibliography at the end. Internal cross-references are included. Maude was sole author of the first two editions (1995, 2007); this third edition, coauthored by Hjelm and Maude, expands on the previous two. It has some 100 pages more than the first edition and is especially strong in politics, international affairs, and biography…. The English-language bibliography is more than 50 pages and broken down into categories (history, literature, and social sciences). Researchers will find the inclusion of scholarly periodical references and websites time-saving. This excellent resource will be a welcome reference for those starting research on Finland, often rated the happiest country in the world. Recommended. All readers.
