ASERL discovery webinar

Tuesday, July 19, 2011 2:19 pm

Today Lynn, Carolyn, Tim, Steve, Susan, Leslie, Jean-Paul, Kevin and Erik got together to attend the ASERL webinar on discovery services. We hear from Wally Grotophorst at George Mason University and Marshall Breeding at Vanderbilt.

Wally talked about the George Mason University experience with Aquabrowser. He discussed some approaches to cross data indexing including just in time solutions (e.g. Metalib, Deep Web), hybrid systems (Primo, Encore, EDS, OPAC) and just in case (e.g. Summon) solutions.

He provided an overview of different perspectives of “just in case” solutions and pointed out that these systems can lead users to approach the system from a perspective that assumes “If we dont have it, you probably dont need it.” another interesting (adapted) quote was: “The value of summon is inversely proportional to the sophistication of your researcher.”

Wally did a great job of looking at the user experience in products like Summon and comparing how libraries are finding ways to bring the benefits of JIC search systems while not losing the value of their catalog-based discovery layers (e.g. Villanova).

Marshall approached the issue by talking about different types of search methods – database specific, federated and discovery products (defined as any system designed to locally index a wide variety of data). He reviewed approaches and data models for centrally indexed discovery products (both local and web-scale) and touched on some of the changes in the ILS that the growth of e-books are likely to bring (e.g decrease in role of circulation, discovery). Marshall suggested that next-generation ILSs may include a tighter integration between back-office systems and discovery layers. This is something the industry is already seeing with OCLC’s Web-Scale management system.

The presentation will be posted online soon on the ASERL website.

ASERL Webinar on Next-Generation Discovery Systems

Friday, February 25, 2011 2:58 pm

Roz, Erik, Ellen M., Kaeley, Craig, Audra, Rebecca, Kevin, Derrick, Susan and Mary S.attended the ASERL Next Gen Discovery Tools session.

The session was an overview of various next-generation discovery systems (e.g Serials Solutions Summon, WorldCat Local and Ebsco Discovery Services among others). ECU reported on their methodology for evaluating and selecting a product (ultimately Summon). They observed that following the launch they added OAI harvested digital collections resources, used google analytics to measure use (OpenURL clicks was used as a measure), and worked with SerialsSolutions to resolve data mapping issues.

ECU also mentioned a recent nice issue of Library Technology Reports by Jason Vaughan at UNLV that reviews these systems.

NCSU followed with an overview of their Summon experience. Libraries in general seemed to recognize that a main purpose of these sorts of systems is to simplify the initial research process but the NCSU folks discussed some of the concerns of advanced users (IL instruction, depth of search features). NCSU showed the percentage of use of a one search system that grouped results (Articles, Books & Media, Website) into different columns. The results showed that over 40% of the time articles were selected while Books and media were a close second at 36%. The website was used around 2% of the time!

Overall a very informative session.

ASERL Lunch-N-Learn #2

Thursday, November 12, 2009 2:23 pm

Today Mary Beth, Jean-Paul, and Erik attended the second ASERL lunch n learn webinar. The speakers were Toby Graham from the University of Georgia and Mary Molinaro from the University of Kentucky.

Both presenters discussed several of the digital collections that their institutions have been working on for the last few years. Interestingly, both presenters talked about newspaper digitization (a project that we have worked on from time to time)!

Toby mentioned the XTF system developed by the California Digital Library and Archivist Tookit as two of their systems. They had indexed over 1M objects using this system!

ZSR library attends ASERL ITDIIG Lunch-n-Learn

Thursday, September 24, 2009 1:26 pm

Lynn, Mary Beth, Wanda, Patty, Jean-Paul, Kaeley, Barry, Chris B. Lauren C., Lauren P, Kevin, Tim and Erik attended the session which was a presentation on how Georgia Tech (Tyler Walters) and Clemson(Emily Gore) approach digitization and digital priorities.

Emily covered what Clemson is doing and presented on her work building a digital initiatives program including MetaArchive, Open LOCKSS, the development of a written preservation plan and a goal to participate in the development community. She briefly covered their beginning use of Archivist Toolkit. She talked about their use of grants and regional grant/collaborations to digitize resources, work with partners to preserve digital resources, and run a ‘regional scan center.’ She mentioned their work to plan a fedora repository and discussed a project called <a href=”http://www.intelligentriver.org/”>Intelligent River</a>, a site that focuses on archiving real-time hydrologic data and data sets in south carolina.

Tyler Walters talked about the Galileo knowledge repository (http:/GKR.library.gatech.edu) which will focus on providing IR hosting via Dspace, workshops, IR services and a collaborative metadata repository. He also talked about Virtual Research Environments which are based on drupal/fedora sites called islandora (http://vre.upei.ca/dev/islandora) that has been developed by the University of Prince Edward Island. Georgia Tech is going to try out a similar approach. He also discussed e-publishing services offered by the library (Epage @ Tech, The Tower).

Tyler also talked about search & discovery approaches including Vufind, metalib (Xerces Xserver), and Tsquared (Univeristy Sakai system) – a project to integrate metalib into Sakai. As he discussed their architecture he mentioned a sun infinite archive solution, sun storagetek 2540 disk array (16 TB), SL 500 Tape library (529 TB), Managed by Sun’s SAM server and ZFS software.

Next ASERL Lunch-n-Learn on November 12th with Mary Molinaro (U-Kentucky) and Toby Graham (U-Georgia)!
