Ability to build a custom PQDT topic-based collection
As a small school with a limited budget, I would like to be able to select a set of topics to include in a PQDT collection. I would be able to select from a menu of topics to include in this collection, and pay for the number of titles I add to the collection. PQDT 5.1M records is awesome, but puts it out of reach for a smaller school.
