To Make the Invisible Visible: eBook Promotion in School Libraries In many ways the circulation of digital library resources (eBooks, and databases especially) is invisible. Collecting usage data for many of the services we subscribe to is only possible in aggregate at the district level (43 school libraries). Additionally the collection itself is mostly invisible to patrons used to physically browsing the shelves. The Kentlake Library staff has made an effort to promote the eBook collection to staff and students over the past couple of years through formal and informal channels (Information Literacy Instruction, Professional Development, Reader’s Advisory and Promotional Signage), but perceived and anecdotal patron reports of usage are still very low or show a lack of familiarity of the services. Traditional promotional activities (such as book talks, booklists, and staff and student reviews) have had a minor impact on overall eBook usage. Library staff h
