elaborate systems of bibliographical classification. If in the future 

 it be found desirable to prepare special hand-lists for the use of stu- 

 dents in the different departments of the Academy this can readily 

 be done by copying the author and subject entries belonging to the 

 several classes as indicated by the class abbreviation written on the 

 upper left-hand margin of the cards. 



Most of the work here reported, apart from the daily routine of 

 the library, has depended on the continued engagement, thanks 

 to a number of liberal friends of the Academy, of Signor Emanuele 

 Fronani whose efficient assistance the Librarian has pleasure in ac- 

 knowledging. In the current work of the year the intelligent aid 

 rendered by William J. Fox is also worthy of note. 



All of which is respectfully submitted, 



Edw. J. Nolan, 



Librarian.

 ments has kept far ahead of the Academy's power to provide suita- 

 ble accommodation, and the time has at last arrived when even ex- 

 cessive crowding has reached a practical limit. The numerous ap- 

 peals for relief, that have been made from time to time, several of 

 them addressed to the Legislature of the State, and which have 

 been but indifferently responded to, have finally met with substantial 

 recognition in an appropriation of $50,000 made by the last Legisla- 

 ture. The hope is held out that a like appropriation, to cover the 

 full amount of the Academy's application to the State for the 

 purposes of a new building, may be made by the Legislature at its 

 next session. 



With the necessities of existing conditions, and the encourage- 

 ment of a friendly response from the generous citizens of our
