Sutro (or his agents) acquired everything that remained of the firm — individual titles published from the sixteenth to the mid-19th centuries, the largest collection of 19th-century Mexican pamphlets and ephemera in the world, an extraordinary collection of imprints and manuscripts relating to the Church in Mexico, and publisher's remainders dating from as far back as the mid-18th century. Sutro also bought the Abadiano ledgers, receipt books and galley proofs dating from the late 18th century. He thus obtained an important collection of documents related to the history of printing and bookselling in Mexico.
