| Many persons have offered valuable advice, but in developing this Historical Atlas of California the authors have had to, in the end, rely on their own judgment. There are so many exciting possibilities for maps covering the history and geography of the Golden State that some had to be omitted, and we know that our final choices will not satisfy all. Some of our maps cover subjects which, although essential to our atlas, have been adequately treated elsewhere. Many, however, have never been properly researched and presented in map form before: for example, readily available sources do not include the location of the Hispanic land grants. In addition, our maps of the Spanish and Mexican expeditions, those of the great Anglo ranchos, and those of the World War II military installations are examples of the many areas in which the authors have had to do primary research and plow new ground. We hope that specialists in isolated areas of California will forgive any unintentional slighting of their interests; the authors had to produce an atlas for the student, the scholar, and those with a general interest in California. |
| A book of this kind must depend on the efforts and expert knowledge of many institutions and persons. This is particularly true when the subject is relatively new and different. Foremost of those to whom we are indebted are the untold number of scholars who have labored in Clio's vineyard for years to produce the many monographs which have been utilized in the preparation of this work. Individuals to whom a special note of appreciation is due include Mr. Granville L. Rogers, Mr. Donald Duke, Mr. Leslie Walker, Professor George P. Hammond, Professor Sherburne F. Cook, Professor John Leighly, Professor Rodney Steiner, Professor Charles A. Bell, and Professor Imre Sutton. |
