The Bureau of Land Management (BLM) is responsible for the protection, distribution, and sales of survey records made by the General Land Office(GLO) and the Bureau of Land Management (BLM) throughout California. Although traditionally, most research involves surveyors interested in the retracement or resurvey of the rectangular survey system, the available information has been researched by historians, genealogists, title companies, and others.
