Many who read history make the mistake of accepting at face value all the information an author presents. This is true of those reading a single history book and those conducting historical research and analysis. In reality, only part of any historical work is uncontested fact; the rest is the author's interpretation or opinion of how and why things happened. In addition, errors of fact can easily be found in most books, articles, or documents due to the author's error or errors in the documents he used in his research. The realization of these failings often causes some readers to go to the extreme of doubting all that they read. History can be of immense value to any reader, including the professional soldier, if these shortcomings are recognized and the facts are carefully sifted. To do this, the reader must critically evaluate the book he is reading or the materials he is using in his analysis. This CSI Report deals with ideas and techniques the professional soldier can use to assess historical materials critically. The soldier can apply this evaluation process to individual history books or the assorted documents, articles, and monographs used in historical research. There is nothing complex or even magical about this procedure. The techniques are basically the same common sense rules or guides the average person uses every day. Essentially, the reader, much as a consumer, is concerned with the quality of the materials used in making the item, the craftsmanship of the person or persons who did the work, and the purpose for which the item was designed to serve.
