Ever set up an IT department library?

I am setting up an IT department library to be used by the 100+ IT professionals in the organization.

The idea is to create a place where to store, catalogue and share all sorts of published material received from vendors or acquired by the employees with company money. That is, technical manuals, training material, certification guides,…

If you have experience in setting up or managing an IT library, please share your advice:

How to manage inventory and borrowing?
How to estimatethe on-going effort required to run the library?
How to motivate team members to bring in their material?

Thank you.
