APPENDIX 3. 
REPORT ON THE INTERNATIONAL EXCHANGES. 
Sir : I heave the honor to submit the following report on the opera- 
tions of the International Exchange Service during the fiscal year 
ending June 30, 1919 : 
The institution submitted to Congress an estimate of $35,000 for 
carrying on the service during the year. This amount was granted. 
In addition, Congress, at the request of the institution, reappro- 
priated the unexpended balance of the 1918 appropriation, amount- 
ing to $712.90, together with the additional sum of $903.68, for 
payment of liabilities incurred in the maintenance of the service 
during the current fiscal year over and above the amount of the 
regular congressional appropriation. Congress also made the usual 
allotment of $200 for printing and binding. The repayments from 
departmental and other establisliments aggregated $1,808.87, making 
the total available resources for carrying on the system of exchanges 
during the fiscal year 1919, $38,625.45. 
During the year 1919 the total number of packages handled was 
270,860 — an increase over the number for the preceding j^ear of 3,914. 
The weight of these packages was 291,918 pounds — a gain of 109,093 
pounds. This large increase in weight as compared with the small 
increase in the number of packages is accounted for, in part, by the 
consignments received for transmission to establishments in France 
and Belgium whose libraries were destroyed during the war, and, in 
part, by the accumulations of United States patent specifications 
received for Great Britain, Belgium, and the northern neutrals. 
The former were forwarded in boxes unopened, each box being 
counted as one package only, and the latter consisted entirely of 
heavy packages. 
The publications sent and received by the exchange service are 
classified under three heads: (1) "Parliamentary documents"; (2) 
"Departmental documents"; (8) "Miscellaneous scientific and liter- 
ary publications." 
The term " parliamentary documents," as here used, refers to pub- 
lications set aside by act of Congress for exchange with foreign 
Governments, and includes not only documents printed by order of 
either House of Congress, but also copies of each publication issued 
by any department, bureau, commission, or officer of the Government. 
The Governments to which this class of publications are forwarded 
send to this country in exchange copies of their own official docu- 
ments for deposit in the Library of Congress.
