Reference for annual journal subscription costs paid per university? Is there any resource that lists how much each university pay in journal subscription fees? I am mostly interested in US universities (E.g. Harvard: $3.5M/year in 2014, MIT: $4M/year in 2006 for science and engineering journals alone), but still curious about other countries (e.g. French universities paid 172M EUR/5years to Elsevier, Finnish research organisations paid a total of 27 million euros in subscription fees in 2015).
There is, in fact, a resource with the information you asked for, for institutions in the United States.

Detailed information on individual academic libraries' expenditures (by university) is available from the National Center for Education Statistics in the United States, as part of their Libraries Statistics Program. 

The data from these surveys, including the individual responses from each university, are available for download in plaintext format at this link. The most recent year available is 2012.

To take your example, according to that data, Harvard's expenditures for library resources in 2008 included $9,248,115 for serial subscriptions. In 2012, this number was up to $16,391,638 (the most of any library in the survey).

If you're interested, a set of related information on amounts paid by selected public universities to specific major publishers can be found in
