REPORT OF THE LIBRARIAN OF THE MICHIGAN ACADEMY 
OF SCIENCE FOR 1911-1912. 
ALEXANDER G. RUTHVEN . 1 
The work of the librarian during the fiscal year was mostly restricted 
to the routine duties of the position. The card index of members was 
revised, the annual report sent out to members and exchanges, and the 
incomplete sets of various members and exchanges filled out. The 
librarian received from the secretary 197 copies of past reports stored 
at the Michigan Agricultural College, which materially adds to the 
reserve stock of each report. We now have all of the reserve copies 
at Ann Arbor, and a card catalog of all of the persons who have ever 
been members of the Academy, with the number of reports which they 
have received. 
Ten institutions have been dropped from the exchange list and ten 
added during the year so that there are now 56S institutions on the 
list. The revised list of exchanges follows :
