The author, Luis (also Louis) R. Goldbaum, was born in Mexico ca. 1871 to a Prussian-Jewish father and a Mexican mother. His older brother, David Goldbaum (1858), was a surveyor who explored much of Baja California and from 1927-30 served as the Mayor of Ensenada. Luis worked as a mining engineer in Mexico and in border towns in Texas and Arizona before settling in the Los Angeles area around 1923. In a one-page introduction to this book he explains: "I have endeavored to give in full to the mining men, prospector, and explorer while in Old-Mexico, a complete, detailed, and general information on the procedures, steps to take, Offices, Government-Departments and Officials to occur and to see, and costs and expenses until acquiring the desired object; illustrating to him complete Mexican-Mining Law of the Republic of the United States of Mexico; and in many other valuable and most needed general information." The book includes both an overview and a more extended digest of Mexican mining law; a list of procedures for obtaining a claim (with specifics for foreigners); information on taxes, assay fees, and other expenses; information on minerals, assay tests, and methods of processing ore; a glossary of mining terms in Spanish and English, and more. A page at the beginning notes that the buyer of this book is entitled to free membership in the "Mail-Consulting Department" of the "Mexican General Advisory Co.," giving said buyer the right to consultation on changes in Mexican mining law "and any other dependable information on Old Mexico matters" for a period of one year.
