I actually consult with faculty members who are signing author agreements with journal publications. The majority of the material that we purchase is journals. We purchase in terms of serials; 78% of what we purchase in the library is journal material. When an academic author is signing with Elsevier or Taylor & Francis, they sign an exclusive licence to these journal publishers, and they receive no fees and no royalties for that use at all. Basically they're getting reputation but they are not getting any money. They work for free.
