From: adam hodgkin <[log in to unmask]> Date: Thu, 26 May 2016 12:39:41 +0200 Dear Colleagues: Can anybody point me to some published research on the breakdown of funds for the acquisition of periodicals (and serials) and books in university and college libraries. I would be interested to have some definite and reliable data on the relative balance between these two types of expenditure over the last 5, 10, 20 or 30 years. I would be interested in the trends by global total, by major regions or countries, or even for specific universities. The global trend would be particularly interesting but I guess it may be hard to discern. I have not been very successful at trying to pinpoint such data sources from Google -- but I am sure some members of the community know exactly where such data can be found. Thanks adam Adam Hodgkin
