FOREWORD Southern California has undergone great and rapid change in recent decades; it has experienced a remarkable cultural and economic metamorphism which gives little sign of abatement. Agriculture and irrigation have pushed back deserts, cities have sprung from b a r r e n spots, and the lands between have been hurriedly laced with rails and roads. Mines have been exploited and raw m a t e r i a l s have developed phenomenally. Heavy industry has mushroomed as a consequence, to say nothing of the great shifts and i n c r e a s e s in population. Such feverish expansion must be carefully charted, fully studied, and intelligently directed if proper order and balance a r e to prevail. There must be a ready consciousness of today's conditions and of tomorrow's requirements. Such consciousness comes only through diligent r e s e a r c h and planning by many agencies and many people working with the fullest complement of r e s e a r c h data available. Accessibility of maps, therefore, is of primary importance. In the absence of all-inclusive collections, the best alternative is a r e f e r e n c e index showing the nature and location of existing maps. In response to this widespread need in southern California, the compiler of this bibliography has collected f r o m widely scattered sources a selected list of maps covering as many of the important subject fields as possible. Here the r e s e a r c h investigator, whether private, governmental, or institutional, can a s c e r t a i n , with minimum effort and maximum coverage, the existence, nature, and location of most of the map information he may need for this a r e a .
