Objectives -This study examines the use of print and electronic collections both before and after implementation of Summon at the University of Manitoba Libraries. Summon is a web-scale discovery service which allows discovery of all of the materials the library owns or has access to from a simple search box on the library's web page.Methods -COUNTER statistics were used to determine database, e-journal, and ebook statistics, including database search statistics (DR1) from the COUNTER Database Report 1, full-text article downloads from the COUNTER Journal Report 1 (JR1), and successful section search requests from the COUNTER Book Report 2 (BR2) for electronic resources. Sirsi, the University of Manitoba's integrated library system, provided statistics on checkouts for the libraries' circulating print monograph and serial collections. The percentage change from the pre-Summon implementation period to the post-Summon implementation period was calculated and these numbers were used to determine whether usage had increased or decreased for both print and electronic collections.Results -As expected, searches in citation databases decreased because searches were no longer being carried out in the native database as the metadata from the database is included in Summon. E-journal usage increased dramatically and e-book usage also increased for four of six providers examined. Print usage decreased, but the results were inconclusive.
