IV PREFACE. 



first words of anonymous titles wlieu entered under an author, and 

 from the first words of all titles in the Indian lano-uages, whether 

 anonymous or not. Manuscripts are entered under the author when 

 known, under the dialect to which they refer when he is not known. 



Each author's name, with his title, etc., is entered in full but once; 

 i. e.j in its alphabetic order. Every other mention of him is by sur- 

 name and initials only, except in those rare cases when two persons of 

 the same surname have also the same initials. 



All titular matter, including cross-references thereto, is in a larger 

 type, all collations, descriptions, notes, and iudes matter in a smaller 

 itype. 



In detailing contents and in adding notes respecting contents, the 

 .spelling of proper names used in the particular work itself has been 

 followed, and so far as possible the language of the respective writers 

 is given. In the index entries of tribal names the compiler has adopted 

 that spelling which seemed to him the best. As a general rule initial 

 capitals have been used in titular matter in only two cases: first, for 

 proper names, and, second, when the word actually appears on the title- 

 page with an initial capital and with the remainder in small capitals or 

 lower-case letters. In giving titles in the German language the capi- 

 tals in the case of all substantives have been respected. 



Each title not seen by the compiler is marked with an asterisk within 

 curves, and usually its source is given. 



There are in the present catalogue 521 titular entries, of which 467 

 relate to printed books and articles and 54 to manuscripts. Of these, 

 4G9 have been seen and described by the compiler — 429 of the prints 

 and 40 of the manuscripts, leaving as derived from outside sources 38 

 I)rinted works and 14 manuscripts. Of those unseen b}' the writer, titles 

 and descriptions of more than one-half have been received from persons 

 who have actually seen the works and described them for him. 



In addition to these, there are given a number of full titles of printed 

 r.overs, second and third volumes, etc., all of which have been seen and 

 described by the compiler; while in the notes mention is made of 69 

 printed and manuscript works, 43 of which have been seen and 26 de- 

 rived from other (mostly printed) sources. 



So far as possible, comparison has been made direct with the respect- 

 ive works during the reading of the proof. For this purpose, besides 

 Ms own books, the writer has had access to those in the libraries of 

 Congress, the Bureau of Ethnology, the National Museum, the Smith- 

 sonian Institution, and Maj. J. W. Powell, and to those in one or two 

 other private libraries in this city. Mr. Wilberforce Eanies has com- 

 l^ared the titles of books contained in his own library and in the Lenox 

 Library, and Mr. Charles H. Hull, assistant librarian of Cornell Uni- 

 versity, has performed a like service for me with the books contained 

 in that institution. The result is, that of the 469 works described de visu, 

 .comparison of proof has been made direct with the original sources in
