摘要:The Library of the College of Physicians and Surgeons of Columbia University has made a study of the cost of its medical journals during 1930- 1931. This was done in order to ascertain the cause of yearly deficits in its budget, which always occurred in the appropriations for subscriptions to periodicals. No difficulties were ever experienced with the allowances for American, British or French journals, but the estimates for German periodicals were frequently inaccurate due to the lack of reliable information concerning the number of volumes to be issued per year.
