Collection Development at OPL

At Oakland Public Library (OPL) in California, we have what we call "coordinated" collection development.  There is a juvenile collection development coordinator who prepares lists with input from all 19 selectors, but all selectors ultimately contribute titles to each list and place their own orders.   The benefit to this is that the librarian on-site has a direct connection to her collection, and that our collections are tuned to the needs of each community, while at the same time drawing on a larger pool of expertise.  The downside is that it does take time to manage 19 selectors in a collaborative process, and we're somewhat at the mercy of the technical/software capabilities of our vendors.  We make all of our selectors through Titletales (BWI, Book Wholesalers Inc.) which we find the most flexible.
