9 Blog Articles on Discovery On Thursday afternoon, Nov 4, 2010 I attended the 45 minute face-off between Serials Solutions Summon and EBSCO s EDS. In the brief demonstration part of the face-off both Summon and EDS were each given 2 searches to conduct as a way to show off their respective products. As opposed to the Q&A portion of the face-off, these searches were not given to Summon and EDS in advance as evidenced by the fumbling of both sides. From my perspective, these demonstrations highlighted the fact that Discovery Services are not really any better when compared to Deep Web Technologies Explorit in terms of the quality of results that they return to the user Deep Web Technologies, Inc. 9

10 What is Federated Search? A single-search interface to quickly find relevant, real-time information from the sources you select that students, faculty, and academic staff need for their research needs Deep Web Technologies, Inc. 10

11 What is a Discovery Service? Discovery Services are capable of searching quickly and seamlessly across a wide range of periodically indexed content provided by participating publishers and may include a library s catalog and other local content in the index Deep Web Technologies, Inc. 11

13 Side-by-Side Comparison Federated Search Real-time search brings back most recent results. Searches and links to full text where available. Search any collection regardless of publisher and includes all of customer s subscribed content leads to efficient searching. Unbiased relevance ranking system is used. Discovery Service Indexed search leads to some lag time for new information. Not always current! Many publishers only provide metadata so unable to search full text. Search only content the Service is able to include in its index lack of transparency. Impartial weighting of results is questionable where service is owned by a major publisher Deep Web Technologies, Inc.

15 Questions to Ask of Summon, EDS and Other Discovery Services Do you have a comprehensive list of what s in the index? Which of my subscription databases are you indexing? For each database how far back does your index go? Are you biasing your results toward Proquest or EBSCO content? Is EBSCO content such as Cinahl available in Summon? How current is your index for my important subscriptions? When are you indexing just metadata vs. full text? Do a thorough comparison of coverage and results returned by various discovery solutions Deep Web Technologies, Inc. 15
