INSTG099 Dissertation Elizabeth Atkinson ii Abstract For several years commentators have asserted that libraries’ traditional OPACs (Online Public Access Catalogues) are failing to meet user expectations. In recent years many academic libraries have implemented discovery layers, systems designed to address the issues of traditional OPACs by allowing e-resources which are not in the library’s catalogue to be searched alongside records in the library’s catalogue and offering a range of features, such as a simple ‘Google-like’ search box, faceted browsing, a “Did you mean…?” feature, suggested alternative searches, user contributions and a more visually appealing interface. Research into how users are using discovery layers for their own research needs is limited. This dissertation investigates how users at Senate House Library are using the discovery layer Encore and which features they find useful. An ethnographic method including observation and interviews is employed to provide an in-depth insight into users’ search experiences. The main findings are that users almost universally start a search using a basic search box, rather than immediately going to advanced search. In contrast to some previous research, several users employed a thorough search approach, carefully evaluating results and looking through multiple pages of results. The idea of location is important to users at Senate House Library. The physical location of search results is not always clear to users who sometimes find a resource in Encore they wish to access only to discover the location it is in is not one to which they have access or is not one to which they wish to travel. Facets are generally found to be useful, but may not be noticed or understood. Content information such as summaries and tables of content are very important to some users. Other features were rarely mentioned or used. Recommendations for further research into the use of Encore at Senate House Library are provided.

OPAC (Online Public Access Catalogue), with a range of features designed to improve the search experience for the user. These OPACs were often referred to as next-generation catalogues. In his 2007 Library Technology Report Marshall Breeding outlined the features which, in his opinion, were expected of next-generation catalogues (Breeding 2007b). These features were: • A state-of-the-art web interface in terms of appearance and navigation • Enriched content, including cover art images, tables of content, summaries and expert reviews • Faceted navigation • Keyword searching • Relevancy ranking • A “Did you mean…?” feature offering alternative spellings • Recommendations for other content • User contributions • RSS feeds for new items and relevant items in other environments, such as a class page in a virtual learning environment Another problem with traditional OPACs was that they only provided access to items in libraries’ catalogues, and not to journal articles and other resources provided by libraries’ subscriptions to electronic resources. An initial attempt to address this problem was the implementation of federated
