WorldBook is now providing webinar-based training for the various facets of WorldBook that are included in the Ohio Web Library. There are two sets of webinars; general ones being offered to U.S. customers at large (the schedule includes the Discover product, which OWL does not get, so take note when registering), and ones geared specifically to Ohio libraries.
