Measuring Outcomes of Collection Use

I will have the opportunity to represent Project Outcome in a panel program at ALA on collections assessment. I would love to hear from anyone who has made an attempt to assess outcomes for patrons of borrowing library materials.

Even if you just have some ideas you haven’t yet had a chance to try out, or if you have measured outcomes for a very narrow slice of your collections, or if you have read some research along these lines, if you had a dream about it – anything you have to share will be welcome.

Much thanks!
