Sept. 1, 2011 – Summon both indexes full-text books, articles, and more from many providers and knows what sources we have online in full text.
Full-text indexing is a powerful way to locate resources on obscure, cutting-edge, or rapidly changing fields of study. Summon indexes full-text articles from numerous journals provided directly from their publishers, as many of our article-indexing databases have done for years. Summon also indexes the full text of conference papers, patents, government documents, and standards. Recently, Summon began incorporating the full-text of books from the HathiTrust Digital Library , a consortium of libraries participating in the Google Books scanning project and other mass digitization efforts.
A default search in Summon will search across the full text of these scanned books that match book records from our catalog. (Turning on the Include results from outside your library's collection facet will search across all HathiTrust books.) While only those books out of copyright (usually books published before 1924) will be available online as an ebook from the HathiTrust Digital Library, Summon will still identify those books in which your search terms appear, so that you can either check them out from us, or use interlibrary loan to get a copy delivered from another library.
Finally, Summon knows what sources are available to use full-text online. Using the Items with full text online facet uses data that also drives our Get VText screens to determine what content is actually available online. Unlike a full-text limiting option in most other databases that limit only to full-text content from that database's provider, Summon's option knows about our full-text content from over 90% of our providers. We often recommend avoiding the full-text limiters in databases, because when the full-text content is not available from that database's provider, clicking the Get VText button will identify when full text is available from another provider. That process happens in the background in Summon, so this limiter is usually very accurate.
