V. REPORT OF THE LIBRARIAN. 

 DECEMBER 31, 1925. 



During the year 1925, the library has been established in its 

 new quarters. There is now adequate room to place the serials, 

 books, and reprints, so that they are readily available. The 

 serial sets, arranged alphabetically by title, begin on the top 

 floor of the stack-rooms and extend down to the center of the 

 middle or reading-room floor. Our reference books begin where 

 the serials end, covering the north end of this same floor on a 

 level with the reading-room. These are grouped under subjects, 

 while the reprints, alphabetical by author in arrangement, are 

 confined to the floor below. A brief directory is placed at the 

 foot of the stairway opposite the elevator and just off the reading- 

 room, and another on the large bulletin in the reading-room. 



In the large reading-room, a current serial rack, having a 

 capacity for six hundred and thirty different serials, now con-

 issues more frequent than yearly. This summer the investi- 

 gators found a list of daily receipts of these serials on the reading- 

 room bulletin. Besides this, the custom of placing the day's 

 receipts all together on a convenient reading table for the after- 

 noon and evening of the day of their arrival will be continued 

 another year. Two tables are reserved for the use of students 

 and near these is a book-case to hold the special reference reprints 

 and volumes assigned by the instructors for reading connected 

 with the courses. An Encyclopedia Brittanica, a new world 

 atlas (1924 Bartholomew edition), and a Webster's dictionary, 

 installed in the reading-room this year, have already proved 

 their usefulness. All new current books remained on exhibition 

 in the reading-room throughout the summer, while a card cata- 

 logue gave the titles of all new books placed on the reference 

 stacks since June of the previous year. 



Besides the establishment of these few useful customs, the 

 summer's experience made clear and definite two very important 

 necessities. First, there must be silence in the reading-room, 

 and second, current serials, current books, and back serial 

 volumes must stay in place for immediate reference. Every
