313 



According to the record of accessions, the total number of books 

 and pamphlets accessioned by the Library up to July 1, 1917, was 

 148,608. From this number, however, should be deducted 5,910 

 volumes which were discarded during the fiscal year 1915 and 321 

 which were discarded during the past two fiscal years, leaving a 

 balance of 142,377 books and pamphlets in the Library on July 

 1, 1917. 



In spite of the unfavorable conditions for the purchase of old 

 foreign books, the Library was able to obtain a number of old hor- 

 ticultural works during the past year, among them several choice 

 gardening books published between 1578 and 1699, as well as many 

 of later date, like the " Complete Body of Planting and Gardening " 

 of William Hanbury (1770-71). Other important acquisitions were 

 the rare " Synopsis Plantarum Aequatoriensium " by William Jame- 

 son, and a set of the " Memorias Economicas " published by the Lis- 

 bon Academy of Sciences from 1789 to 1815, which contains a number 

 of papers by Loureiro and Vandelli. 



CATALOGUE DIVISION. 



Helen M. Thompson, Chief. 



The record of the material classified and catalogued during the year 

 is as follows : 2,590 volumes, 508 pamphlets, 5,783 serials and con- 

 tinuations, and 5 maps and charts, malving a total of 8,957, a de- 

 crease of 793 from the preceding year. In addition to the complete 

 cataloguing of the above books, pamphlets, and maps, author cards 

 were made for 216 pamphlets and 1,178 " reprints." The pamphlets 

 for which only author cards are made are those of less importance. 

 They are arranged by subject in a separate pamphlet collection. 

 The " reprints " or " separates " of articles from periodicals are 

 also filed in a separate collection which is arranged alphabetically 

 by author. 



There were added to the main (dictionary) catalogue 22,875 cards, 

 and 3,713 were withdrawn, making the net addition of 19,162, a 

 decrease of 2,461 as compared with the preceding year. It is es- 

 timated that the main (dictionary) catalogue now contains ap- 

 proximately 370,000 cards.
