Two thousantl and twenty volumes have been bound during the 

 year, making a notable improvement, especially in the department of 

 journals and periodicals. The shelf list in this department has been 

 completed and will be of use, not only in taking stock, but in any 

 rearrangement of the volumes which may be hereafter necessary. 

 The general card catalogue has of course been kept up to date. In 

 connection with the preparation of work for the binders constant 

 ■effort is made to secure supplies of deficiencies, in many cases with 

 gratifying success. 



The necessity for more room becomes every day more urgent. The 

 growth of certain departments has heretofore been provided for by 

 encroachment on the study rooms. This has been so manifestly to the 

 inconvenience of those occupying the rooms that some of these books 

 have been removed to shelving placed above the cases. These shelves 

 have to be reached by ladders, and the arrangement is only tolerable as 

 a temporary relief from crowding. It is believed that ample pro- 

 vision for at least storing accessions will be provided in the proposed 

 new building, a large part of which will be designed for the erection of 

 tiers of stacks. 



The proofs of the Union List of periodicals in the libraries of Phila- 

 delphia have been read, and the work will be issued early in March 

 under the auspices of the Free Library. It will be of the first import- 

 ance in cooperative work. 



It is gratifying to know that the present arrangement of the Library 

 was warmly commended by the members of the International Congress 

 of Zoologists, who were entertained here last September. 



The Librarian read a paper on the use of books on Natural History 

 at the Conference of the American Library Association, held at Ashe- 

 ville in May. The paper has been published in the first volume of the 

 Bulletin of the Association. 



Acknowledgment is again gladly made of indebtedness to the 

 Assistant Librarian, William J. Fox, for efficient service both in the 

 Library and the Publication Office. 



Edward J. Nolan, 



Librarian.
