I had issues with the Rough Guide to Japan that I used 2 years ago and unfortunately this book disappointed me in similar ways. First off, the errors. I only read the sections on Stockholm, Uppsala, and Gothenburg and surroundings, in addition to the Basics, Contexts, Glossary, etc., but in these I found numerous errors, particularly in the maps. Rough Guides maps use legends with numbers for food/drink establishments and letters for lodging. But you'll see, for example, the letter J listed in the legend but missing from the map, or another letter or number has been placed in clearly the wrong spot on the map. I also found Swedish spelling errors and mislabeled photos. I am convinced that this series is poorly edited. Anyone could crosscheck the maps in 1 day and catch the errors. But this crucial step in publishing seems to have been skipped.
Additionally, something that strikes me about the Rough Guide series is that the authors tend to be older and male, and their recommendations do not always suit female travelers or younger travelers. The authors are also rarely country natives. The main author listed for this edition does seem to have experience with the country, but the coauthor does not. Just because someone has a background in journalism and likes to travel does not qualify them to write about a specific country or to provide up-to-date information that will suit a wide range of travelers. And if you can't find a country native to author the guide, at the very least you could get a native to give it a look-over and catch the errors.
Also, there is little to no information in this guide on shopping - more evidence of the lack of any female input. I do not need long narratives on shopping, just a few bullet points on the main shopping areas or popular stores.
I admit I am rarely happy with any travel guide. I feel that too much time is spent detailing the dishes available at various restaurants or explaining the sights of remote towns I will never visit, and not enough space is devoted to truly helpful information and tips for navigating an area and saving money. I wish more guides would focus on budget travel and pull in the reigns on extravagant splurges. I also request more content on the present-day reality and culture of a country and less info on their medieval history. This guide is no exception.
That being said, the things I do like about this guide are its compact size, its focus on public transportation, the colorful photo section, the Contexts section, the Useful Words and Phrases, and the Swedish Glossary. I checked other guides to Sweden and these elements were missing. For that reason I give it 3 and not 2 stars. But it is a very reluctant 3 stars.
