ABSTRACT
For many decades librarians have attempted to measure use of serial collections and the advent of electronic journals has opened up new avenues for measuring use. However, many vendor-supplied usage statistics are unsatisfactory. Two Yale University librarians tried another approach and conducted a citation analysis to compare usage before and after the arrival of electronic journals. They wanted to answer a basic question: Did the purchase of electronic journals not previously held in print affect citation patterns of Yale authors?
