Spiteri, LouiseTarulli, Laurel2011-10-242011-10-242011-01-01http://hdl.handle.net/10222/14298Originally published in the Proceedings of the Canadian Association of Information Science found at http://www.cais-acsi.ca/proceedings/2011/16_Spiteri_and_Taruli.pdfThis paper uses transaction log data to examine how library users interact with two social discovery systems used in two Canadian public library systems. Results indicate that user-generated content is not used extensively or significantly in the two social discovery systems. Format is the predominant facet used to refine searches; the remaining facets are significantly underrepresented.enSocial discovery toolsSocial mediaCataloguingMetadataText
