THE TABLES. 



The Tables in this work are elaborated from the card shelf list used 

 in this Librar}'. All the necessary bibliographical information is 

 appended to the entrj" of a publication or series, and no time or effort 

 has been spared in the attempt to make these Tables present an accu- 

 rate and complete list of all the publications of the Department from 

 1862, including all 1902 imprints. 



When a publication was also issued as a Congressional document the 

 Congressional reference is inserted after the entry for such publication 

 in the Tables. In a few instances a single paper in a volume has been 

 so issued, and in those cases it has been necessar}^ to insert the 

 Congressional reference in the Index. 



Those publications which emanated from the Department, but which 

 were issued only as Congressional documents, are listed chronolog- 

 ically in the Appendix to this work. 



The titles in the Tables are exact copies of the title-pages of the pub- 

 lications with the omission of unnecessary articles. In case of 

 "general publications" or other series which are classified alphabet- 

 ically the subject words are introduced as headings and the title follows 

 as it appears on the publication. 



In counting the maps, plates, charts, etc., in a volume the total 

 number has been stated as " plates," except in cases where the character 

 of the illustration was plainly determined by numbering. 



When the word circular "(circ.)" appears at the end of an entry it 

 indicates a one-page publication of uncertain size. 



THE INDEX. 



The Index, which forms the most important as well as the larger 

 part of this work, has been carefully compiled with a view to quick 

 reference to any special author, subject, or title. In dealing with a 

 collection of publications differing so widely in their sul)ject-matter, 

 and for the most part of a scientific character, it has been found diffi- 

 cult to determine the best form of entry in man 3' instances for papers 

 with meaningl(\ss or strictly technical headings, cspiM-ially when a 

 reading of the paper ])y one unac(|uainted witli tlie subject treated has 

 proved equall}' unsatisfactory in suggesting a suitable title. There are 

 doubtless omissions on account of these nondesci-ipt titles, which, to 

 save time, have been used for the Index entries. Only where titles
