The Mural Conservancy of Los Angeles maintains a FREE database of Los Angeles' Mural History linking artists, murals and neighborhoods.
The foundation of this database was shaped by Robin Dunitz' book "Street Gallery", the first true compilation of Los Angeles public murals.
The MCLA website allows submissions of murals created recently in Los Angeles, forming an ever growing archive joining the historic with the new.
