What are Discovery Tools? A discovery tool provides a single point of access to a range of library resources that enables users to search multiple resources with a single search. Some Examples: EBSCO Discovery Service Summon service (Serial Solutions) AquaBrowser Library (Serial Solutions) Encore Discovery (Innovative Interfaces) Primo Central (Ex Libris Group ) Blacklight – open source University of Virginia
Reasons why you might want a discovery tool1. Simplify the research process with a single search.2. Market locally created databases to your community to increase visibility and use.3. Provide a more intuitive search interface that encourages discovery. No more complex searching that confuses users.4. Improve the “depth” of the metadata to index content not included in your catalog.5. Integrate Web 2.0 options with your search engine, e.g. tagging, reviews. Give your searchers a reason to return to your site.6. Enhance remote access to your library.7. Make searches successful8. Promote the library as a quality research source that meets the changing expectations of our users.

Do your homework• Who do you expect to use this tool?• How are you going to build on your catalog?• What resources to do want to bring together?• How do you want to integrate with other services and products?• What are your preferences for integrating the results? For authentication? for example, with articles – they can be integrated, separated, or faceted.• Talk to librarians using the system – try to get a login to demo
