Past enhancements
May, 2012 -- UNC Digital Collections enter the TRLN Endeca indexes In early May, UNC began contributing metadata for locally digitized materials to the TRLN Endeca indexes. Metadata for over 25,000 digitized oral history interviews, North Carolina college yearbooks, maps, and historic postcards are harvested from UNC's ContentDM system via OAI-PMH and indexed and presented with published materials through Search TRLN and the UNC Catalog. The North Carolina Postcard collection is one collection that is now searchable alongside published materials. Search TRLN also includes a new experimental primary sources facet that has been added in conjunction with this change. The experimental facet allows patrons to limit a search to primary sources including digitized materials from UNC and manuscripts, archival collections, and primary materials found in published sources from all four TRLN institutions.
March 12, 2012 -- Enhancements Document delivery requests are now available from results lists as in the example search for 'Baseball' MARC records for the Early English Books Online collection entered the TRLN Shared Records program
July 21, 2011 -- Search TRLN now provides hyperlinks to digitized versions of books available at HathiTrust and the Open Content Alliance. Search TRLN users may see a link to HathiTrust or the Open Content Alliance results in Search TRLN. Following the hyperlink allows the user to view the full-text of works in the public domain.
May 2011 - Search TRLN promotes Open Access resources Search TRLN indexing routines and user interface changes now automatically identify and promote open access electronic resources. The 'urls' for these resources are labelled Open Access resource and do not require authentication. Over 200,000 electronic resources in the Search TRLN indexes have been identified as Open Access through these processes.
February 2011 - Shibboleth authentication supported for TRLN institution affiliated users Search TRLN now supports Shibboleth authentication protocols for faculty, students, and staff who are affiliated with Duke Universtiy, North Carolina Central University, North Carolina State University, and the University of North Carolina at Chapel Hill. Users can 'login' using their campus network ids to gain access to custom services on Search TRLN. Current benefits to users include streamlined access to document delivery and bibliographic management applications. This proof-of-concept project demonstrates the feasibility of inter-institutional authentication at the TRLN-level that can support future projects.
September 1, 2010 - Autosuggest feature added to Search TRLN Users of Search TRLN can now take advantage of an autosuggest feature initially implemented by the UNC Chapel Hill Libraries. As the user types search terms the system provides suggested title, subject, and author terms. Over 11 million headings from the catalog records of the TRLN libraries are used to generate the suggestions. Try this feature at Search TRLN.
August 2010 - Changes to indexing routines The TRLN Endeca System indexes approximately 12 million catalog records from the Duke, NCCU, NCSU, and UNC integrated library systems. The index is rebuilt every Sunday morning. This process is usually complete by noon each Sunday. Every hour, the TRLN Endeca System receives updates from the Integrated Library systems at the four institutions. These changes include new bibliographic records, changes to bibliographic records, changes in circulation status, or the removal of records from the index. These changes are processed every hour between noon on Sunday and Saturday night at midnight each week. The changes can be seen in the indexes at 30 minutes past the hour. More details regarding the frequency with which various update activities occur are documented at TRLN Endeca Data Status.
April 2010 - NCCU Catalog Patrons affilated with NC Central can now take advantage of an Endeca driven catalog specifically scoped to the collections at NCCU. The NCCU Catalog supports the same set of features available to users of Search TRLN. View this new service at NCCU Endeca Catalog.
February 2010 - Related Author Suggestions Search TRLN now provides users with 'Author Suggestions' related to a user's query. This feature is intended to help users disambiguate among authors with similar names and take advantage of cross-references. The service is dependent upon the OCLC WorldCat Identities service which includes a 'summary page' for every name in WorldCat. TRLN's author suggestion feature queries a WorldCat Identities web service for the user's search term and returns the six most relevant and popular headings associated with the search. Headings are displayed as hyperlinks at the top of the results list to allow users to search for these headings in Search TRLN. Fuzzy matching and weighting based on the number of holdings associated with a heading drive the generation of relevant headings for users to choose from. View this feature in action at Search TRLN. If you have feedback to provide on this feature, please do so at Search TRLN Comments.
January 16, 2010 - Related Search Suggestions Search TRLN now provides users with 'Related Search Suggestions' based on the results of the users search. This feature is intended to help users find all relevant resources in the Endeca keyword search environment. Related subject searches are derived from the most frequently occuring subject headings within the records in the current results list. As the user navigates through the results list, related searches are dynamically updated and displayed above the results list. If you have feedback to provide on this feature, please do so at Search TRLN Comments.
Week of July 27th, 2009 The EAD Indexing Task Group has been working on methods to incorporate archival finding aids encoded using the Encoded Archival Description (EAD) standard into Search TRLN. TRLN archivists have created several thousand EAD finding aids providing detailed descriptions of archival collections to support scholars using these collections. Search TRLN now indexes and displays key data elements from the consortium's EAD finding aid documents. See for example the Search TRLN record for the GI Bill Oral Histories Collection at NCSU. Over the next several weeks the remainder of the consortium's EAD finding aids will be indexed in Search TRLN. When complete this project will enable the discovery of archival materials alongside published materials and enable the cross-searching of all of TRLN's 6,500+ EAD finding aids from a single search interface.
Week of April 6th, 2009 - Enhanced indexing support will be implemented for terms that include diacritics and special characters beyond the Latin-1 character set. Diacritics will now be ignored in searching so that searches for terms with and without diacritics will return the same result sets. Apostrophes will now be ignored during indexing and searching processes. Searches for terms with apostrophes will also be subject to stemming. For instance a searches for "loves labours lost", "love's labours lost", and "love's labour's lost" will return the same result sets. Previous versions of TRLN Endeca did not display repeatable fields, such as summaries, in the correct order. In this upgrade, libraries can choose to modify their MARC extracts to support this feature.
February 1, 2009 -- A 'British-American' word forms file was implemented on the TRLN Endeca servers. This modification supports retrieval for terms with British and American spelling variations. For instance, a search for 'colour' will also return matches on 'color.'
December 19, 2008 -- Search TRLN now supports the ability to add records to a 'Marked Item List' and to print, email, or export those records to citation management systems like Refworks and Endnote.
November 20, 2008 -- Search TRLN now supports retrieval of titles and authors containing non-ASCII characters.
November 5, 2008 -- Search TRLN now supports email, text messaging, and printing of single records. Also, patrons have the ability to export records directly to Refworks or to RIS format for Endnote. See The Tar Heel state : a history of North Carolina for a preview of these features.
September 26, 2008 -- Search TRLN now supports searching by Journal Title. Exact title searching has also been improved. See for instance this search for the title The way things work.
August 20, 2008 -- Search TRLN now supports links to digitized versions of books available at Google Book Search. Search TRLN users may see a link to Google Book Search when viewing a full record for a title. Following the hyperlink allows the user to preview digitized copies of works under copyright protection and full-text of works in the public domain.
August 13, 2008 -- Search TRLN now supports 'tokenized' searching for Chinese, Japanese, and Korean language materials enhancing access to these materials in the TRLN collections.
