Mr. Thomas W. Field issued in 1873 _An Essay towards an Indian Bibliography, being a Catalogue of books relating to the American Indians_, in his own library, with a few others which he did not possess, distinguished by an asterisk. Mr. Field added many bibliographical and historical notes, and gave synopses, so that the catalogue is generally useful to the student of Americana, as he did not confine his survey to works dealing exclusively with the aborigines. The library upon which this bibliography was based was sold at public auction in New York, in two parts, in May, 1875 (3,324 titles), according to a catalogue which is a distinct publication from the _Essay_.[86] The collection of Mr. Almon W. Griswold was dispersed by printed catalogues in 1876 and 1880, the former containing the American portion, rich in many of the rarer books. Of the various private collections elsewhere than in the United States, more or less rich in Americana, mention may be made of the _Bibliotheca Mejicana_[87] of Augustin Fischer, London, 1869; of the Spanish-American libraries of Gregorio Beéche, whose catalogue was printed at Valparaiso in 1879; and that of Benjamin Vicuña Mackenna, printed at the same place in 1861.[88] In Leipsic, the catalogue of Serge Sobolewski (1873)[89] was particularly helpful in the bibliography of Ptolemy, and in the voyages of De Bry and others. Some of the rarest of Americana were sold in the Sunderland sale[90] in London in 1881-1883; and remarkably rich collections were those of Pinart and Bourbourg,[91] sold in Paris in 1883, and that of Dr. J. Court,[92] the first part of which was sold in Paris in May, 1884. The second part had little of interest. * * * * *
