Thanks for putting this list together. The lack of depth only further shows the need for the collective library “us” to direct resources into research on these issues and the savvy communication of findings.

Just to clarify, the CACUL Benchmarks are essentially just a different way to present existing CARL data (and some existing regional data) so any Cdn academic/college library can understand their traditional output numbers (that CARL defines and collects for CARL members) in the context of others. ARLs and CARL members take this for granted because they have easily accessible annual ranked lists to look at; not so for all our Cdn colleagues. So, they are not about describing value but not without value for libraries looking to better understand where they sit on CARL-defined measures.

I think your literature scan is write in not finding much in terms of impact. Measuring the number of Library website visits or book checkouts is a fine place to start, but the more important (and difficult to answer question) is whether that resource made education or research better.
