The American Society for Information Science and Technology (ASIS&T) has been the society for information professionals leading the search for new theories, techniques, and technologies to improve access to information since 1937. ASIS&T's southern California chapter began life in 1961, when it was chartered as the Los Angeles Chapter of the American Documentation Institute.

The LACASIS&T community is a widely dispersed regional chapter that spans California, Hawaii, New Zealand, and Australia. Though headquartered in Los Angeles, LACASIS&T aims to bring programming and provide support to ASIS&T members in the Southern California and Pacific regions.
