The Library received an increased number of requests for mate- 

 rials on biological science and anthropology, especially on scientific 

 developments in countries behind the Iron Curtain. This year, more 

 than in the past, visiting scholars used the Museum Library. A 

 marked increase was noted in the use of our facilities by university 

 students, many of whom were doing graduate work, and by others 

 whose projects were of a scholarly nature. Miss Eugenia Bernoff, 

 Reference Librarian, is especially capable in helping readers to find 

 what they are seeking and in giving accurate information over the 

 telephone. Her ability to work with foreign languages is especially 

 valuable in these services. More than 2,170 reference inquiries were 

 handled during the past year and more than 2,000 volumes were used 

 in the General Reading Room by visitors (a record of volumes used by 

 staff members is not kept). Miss Louise Friedal and Miss Her- 

 mine F. Tworkov, Antioch College students, assisted in clerical work. 



Among arrangements for getting materials necessary for an ade- 

 quate research library is the exchange system (see page 99). Contin- 

 ued effort is made by our Library to acquire systematically, through 

 exchange on a worldwide scale, currently issued publications of learned 

 societies, academies, and institutes, and our network of exchange 

 sources now extends into regions where research has been limited or 

 stopped until recent years. Active exchanges of publications total 

 991 in comparison with 401 paid subscriptions. A systematic review 

 of periodical subscriptions was made for transfer, wherever possible, 

 to the exchange list, and some economies were achieved thereby. 



The transfer of a large part of the map collection from storage 

 crates to the new map cases in the General Reading Room was com- 

 pleted during the year. Some 38,000 maps were sorted, filed, and 

 arranged in systematic order under continent, country, locality, and 

 city by Chih-wei Pan, an assistant, and a card file has been made. 



The Library continued to make materials available to other li- 

 braries through interlibrary loans. In return we enjoyed the benefits 

 of this important service that enables libraries to supplement their 

 own resources with those of other institutions. A total of 320 books 

 was borrowed and lent. The use of photostats and microfilms in- 

 creased notably during the year. 



The Library's present rate of binding is keeping pace with current 

 accretions of unbound materials and is reducing the arrearage of ma- 

 terials in need of rebinding and repair. Altogether 1,158 volumes 

 were prepared for binding during the year and numerous pamphlets 

 were placed in binders. Repairs were made in the Library on 901 

 volumes at a saving in commercial-binding costs of approximately 

 $2,500, and 3,338 volumes were lettered with the electric stylus.
