Query: Totally out-of-date

I was careless and didn't note the copyright of this book--1992--or the dates on the previous reviews. In 1992, the activities would have been fine; but when the book discusses the formation of the European Union as a work in progress or shows Yugoslavia as a country of Europe or describes the economies of countries with 17-year-old data, at least half the book is totally unusable. I do not understand why this book has not been updated because if it had, it would be a valuable addition to any geography classroom.
