FIFTEENTH REPORT. 
REPORT OF THE LIBRARIAN OF THE MICHIGAN ACADEMY 
OF SCIENCE FOR THE YEAR 1912-1913. 
ALEXANDER G. RUTHVEN.* 
The work of the librarian during the fiscal year has consisted prin- 
cipally of the routine duties of his position. Considerable time has been 
expended in the correspondence with exchanges and the sending ont 
of reports purchased by members and others, but the results are satis- 
factory. Seventeen exchanges have been added to the list as against 
thirteen dropped. A nunjber of reports have been sold, and several per- 
sons have applied for membership in order to receive the reports. 
The annual report for last year (1911-1912) could not be sent out, 
as it is still in the hands of the printer. 
The first report of the Academy (1894-1S99) is now practically ex- 
hausted. There are but six copies in our possession, and these have 
been set aside that the Academy may not be without a few complete 
sets of the reports. 
The present list of exchanges is appended:
