THE LIBRARY. 727 



haps be advisable to transfer the work to the Division of Publications 

 if some satisfactory cooperative arrantz;ement can bo made with the 

 Division of Publications and the various bureaus and offices whereby 

 the Library may have the same facilities for obtainin^j exchanges 

 that it now enjoys. The time which the work in connection with 

 the mailinp: lists and the distri])ution of publications has hitherto 

 rcfjuired of the Library could then be spent to greater advantage on 

 that part of the work more closely connected with the activities of 

 the Library, namely, the work of obtaining exchanges. 



It is gratifying to note that there is apparently an increasing 

 willingness on the part of the bureaus and ofiices of the Department 

 to cooperate Nnth the Library in the matter of exchanges. Their 

 willingness to have them addressed to the Library is especially appre- 

 ciated, as the Library is thereby better able to keep the files complete 

 and up to date. It is also most desirable to have in one place infor- 

 mation in regard to all the publications received at the Department. 

 This arrangement in regard to exchanges, which may perhaps not 

 unfittingly be described as a pooling of interests, undoubtedly works 

 to the mutual advantage of the bureaus and ofhces of the Department.
