The California Records of Big Game (C.R.B.G.) is dedicated to recording big game animals of California that are legally taken on Golden State lands. Deer are separated by species and subspecies into seven categories: Coastal Columbian Blacktail, Inland Columbian Blacktail, Rocky Mountain Mule Deer, California Mule Deer, Inyo Mule Deer, Burro Mule Deer, and Southern Mule Deer. Antlered game will be scored as typical and/or non-typical and entered as such. All game entered will be placed in one of five divisions according to the method of take (modern rifle, archery, muzzleloader, handgun, traditional archery).

.
C.R.B.G. will show the largest game animals that inhabit the Golden State with pictures of the highest-ranking animals in each division. Article clips and professionally written stories will be used to tell how these top trophies were taken.

State game agencies and hunting organizations will be listed as well as guides, outfitters, and big game hunting clubs.

There is no charge or fee to enter, however  quality prints and/or digital pictures  are required for all game. Prints showing a front view and two side views are recommended. At least one (unaltered) field photo is required, and the appropriate, validated, California big game tag or photo copy of such must be presented for all "Top 10" candidates. For Blacktail and mule deer submit a picture of their flank (tail) end if possible.

Some of C.R.B.G.'s deer boundaries are flexible allowing for questionable entries to be examined, and using the photos and other physical evidence the C.R.B.G. attempts to place each animal into their biologically correct category. .

All entries must be measured using the Safari Club International (S.C.I.) scoring system by an S.C.I., Boone and Crockett (B&C), or Pope and Young (P&Y) official measurer. After the book is published the C.R.B.G. would like to congratulate hunters with a certificate showing their name and rank of their big game animal in the California Records of Big Game.
