to the office ol the Library and the stack room is on thr ^^find floor. 

 The four departmental hl>raries are located on the third flcxir in rooms 

 n ' X fach of the depii •*;. The task of installing the exhibi- 

 tion luuls has employed all ii 1 wiuce av.-'-' '■ and the work of shelv- 

 inK the lib'-i-i--: i; in alieyancc until t:.. — ick rooms can be oom- 

 pictcd whc: . ; .il>Ie time and lal)or will be necessary to retetablish 

 the sequence of the original classification. The decision to have all 

 literature pertaining to the work of the departments placed in their 

 respective libraries necessitates a numlxr of transfers and until these 

 transfers arc effected and inventories taken it is not possible to ac- 

 curately state the numlKT of books and pamphlets in each library. 

 Tlie books of the anthrojxiioj^ical and botanical departments have been 

 placed on the shelves. In the Dqmrtment of Anthropolojjy discarded 

 exhibition cases were converted into lxx>k cases and used to good 

 advantage. Tlie library's generous patron, Mr. Edward E. Aycr, pre- 

 sented the rare eight volume edition of Audulxjn's Birds of North 

 America. During the year Mr. Aycr caused to be ordered one hundred 

 and fourteen volumes of ornithological works. Of these eighty-one 

 volumes have been received, a number of which arc rare copies dating 

 back to 1776, and all arc beautifully illustrated. A catalogue of all 

 the ornithological works in the library is in preparation, at the request 

 of Mr. Aycr, who has cxprcssc<l a desire to supplement his already 

 RTili-Tuli.! collection until it provides workers and students with as 

 C' .o an oniithological reference library as is obtainable. Gifts, 

 gratefully received from other sources, are acknowledged as such in the 

 list of accessions appended to the report. Exchanges were received 

 from four hundred and ninety-six institutions and indi\iduals. The 

 first consignment of the jniblications of the Museum, since pre-war days, 

 was forwarded during the year to all countries where international 

 exchange service has been resumed. The continued upward trend of the 

 cost of all publications very seriously affects scientific literature. Various 

 srx-ii tir^ that have existed mainly for the publication of the results of 

 B' .  research have had to either .suspend publishing for the time 

 being or discontinue exchange relations and ask for subscriptions to 

 enable them to continue their work. Five new exchanges were effected 

 with the following: Federated Malay States Museums, Kuala Lumpur; 

 Musco de Etnologia y Antropologia de Chile, Santiago dc Chile; 

 Omithf)' * ty of Japan, Tok>'o; Manchester Geographical 

 Society ui uu^iiund, R. Academia de Ciencias y Artes, Barcelona. 

 ComparatiNfly few purchases of books have '— " made as the time of 

 the stafi ha- V.rcn wholly occupied w-i*h ir .;on work. Subscrip- 

 tions were » 1 for seventy-eight 1 ■>.'.-.
