New Circulation Modeling Results August 4, 2017August 4, 2017 rburke Leave a comment We just completed a long-awaiting transition to a database backend for the Reading Chicago Reading data. One of the big changes was the discovery that we had been using incorrect holdings data for one of our books. So, some of the modeling results are now slightly different, and the anomalous results for “Gold Boy” are now gone. This change also means that we will now be able to process circulation data for books that are not OBOC selections including the books that were chosen as CPL recommendations. We will also be able to explore some new aspects of the circulation data such as the way books circulate between branches and the length of time that books are checked out.
