A 1974 study over a 4-month period (January-April) of free MEDLINE use at Oakland University (Rochester, Michigan), a university without a medical school, involving 21 faculty and students for a total of 36 searches, showed that, although 54% of the citations considered relevant by the user were not available in the university library, only 4.1% of the citations were requested through ILL.

A survey reported in 1977 concerning online searching at the U.S. Army Construction Engineering Research Laboratory library (Champaign, Illinois), involving both users of the service (sample size: 27; responding: 26 or 96.3%) and nonusers of the service (sample size: 19; responding: 13 or 68.4%), showed that, of 25 user respondents, 11 (44%) reported ordering “many” of the documents for the citations from the online search through the library; 9 (36%) reported ordering “a few”; and 5 (20%) reported ordering “none.” (Source)
A 1978 survey of North American health sciences libraries that were users of the National Library of Medicine search services in November 1977 (survey size: 708 libraries; responding: 376; usable: 345 or 48.7%) showed that, of 337 respondents, 316 (93.8%) libraries “agreed” or “strongly agreed” that online searching had made it possible to serve more users, while of 330 respondents, 311 (94.2%) libraries “agreed” or “strongly agreed” that online searching had caused an increase in interlibrary loan borrowing.

A study reported in 1978 of LEXIS subscribers in 4 different cities (Cleveland, Chicago, New York City, and Washington, D.C.) (sample size: 62; responding: 39; usable: 38 or 61.3%), involving 35 law firms, 2 law schools, and 1 government agency, showed that6 (15.8%) respondents reported an increase in interlibrary loan borrowing since they began to use LEXIS, 1 (2.6%) reported that interlibrary loan borrowing decreased after they began to use LEXIS, 30 (79.0%) reported no change in interlibrary loan borrowing, and 1 did not reply to this question.
