The original Lawrence & Houseworth photographs were mounted onto bond paper by the Library of Congress. Many of them are faded. The original photographs are filed in LOT 3544, arranged by the number associated with them in the Gems of California Scenery catalog. A copy of the third edition of the catalog is also filed in the LOT. Earlier editions of this catalog are not available in the Library of Congress.

The Library made copy negatives and prints for all of the original photographs. The copy photographs are also housed in LOT 3544, organized into subdivisions by location and/or subject. The subdivisions are listed below.
