Sources of the African Past is designed for use in a wide variety of courses and in conjuction with other texts. The authors have kept their own interpretations to a minimum and invited scrutiny of their decision of selection and arrangement. They chose the cases on the basis of several criteria: geographical coverage, abundance and diversity of primary sources, importance in the secondary literature, and relevance to important historical problems. All the studies emphasize political change. All witness some growth in European intervention.
In selecting the documents, the authors sought a balance of perspective without sacrificing accuracy and relevance. This means a conscious effort to present a variety of views: African and European, internal and external, partipant and observer, those of the victims as well as those of the victors, those of the "people" as well as those of the elite. Within the limitations of space, they have made the excerpts sufficiently long to allow the reader to examine the author's style, purpose and other characteristics. Keeping in mind the limitations of libraries, they have attemted to make each chapter self-contained.

The author's very personal view of an expat's life in Luxembourg is not overbearing, and even the most informed reader will learn something new about the history of the Grand Duchy, its bureaucracy and social conventions and attitudes. The book is brimful with little snippets of useful information and trivia for those unfamiliar with the country, and Robinson's anecdotes will spark empathy with readers who live, or have lived, in Luxembourg. -Duncan Roberts, editor of 352 Magazine.
