Discovery Layers for CONTENTdm

A presentation for the American Library Association 2010

Conference, Washington DC,by Edward Iglesias

What is a “Discovery Layer”?

... a Discovery Layer allows a user to search across a library catalogue (or several), an ebook platform (or several), and a source of articles (or several).

• A Discovery Layer could make use of one or more combinations of the following:• Federated Searching

– a query is distributed to multiple sources, and responses are compiled, de-duped, and returned

– e.g. Sirsi Single Search • Metasearching

– a single, regularly complied index is created from the collection of metadata from multiple sources

– e.g. Endeca, Google• Single host environment

– metadata and content are placed on a common server– e.g. WorldCat, Ontario Scholars Portal

What is the Discovery Layer to CONTENTdm?

• The place where your users come from• Google or Other Search Engine• OPAC• Worldcat• Website

How did we get into this mess?

• Thesis Scanning started ~2000• Purchased LUNA Image Server in 2004• 2004 Electronic Submission of Theses became

mandatory• Some Student Publications attached to item

records in ILS• Lots of scanned items on web servers

And now?

• LUNA still there, for now• Eprints gone migrated to CONTENTdm • All Student Publications migrated to

CONTENTdm • Veteran’s History Project Added in

coordination with Library of Congress

The result, one interface

What do we have?

• CCSU Student Publications• This collection features Central Connecticut State University student newspapers and literary publications from the 1940s through the present, as well as a

selection of Dial Yearbooks (1926-1996). • CCSU Theses & Dissertations• This collection contains the full text of select Central Connecticut State University master's theses, dissertations, and special projects submitted since 2002.• GLBTQ Archives • These videotaped interviews form part of the Gender Equity Collections housed at the Burritt Library. In addition to the videos, the collection also includes

manuscripts, letters, photographs, books, buttons, T- shirts, videos, postcards, flyers, and periodicals by and about Gays, Lesbians, Bisexuals, Transgendered and Queer. The collection is particularly strong in materials by and about Connecticut's GLBTQ communities, and religion and the gay community.

• O'Neill Archives Oral Histories• The O'Neill and Lemon Law oral histories are significant for their impact on Connecticut governing initiatives that reverberated nationwide, of which the seminal

Lemon Law legislation, designed to protect consumers from fraud and abuse by auto manufacturers, is a prime example. The interviews also focus on the administration of Connecticut Governor William A. O'Neill (1980-1990), whose humanitarian and environmental policies were notable for the era. During his tenure Governor O'Neill tackled a myriad of issues, from clean drinking water and assistance for the mentally challenged to appointing the first female Chief Justice of Connecticut's Supreme Court.

• Polish American Pamphlets• Since its establishment in 1986 the Connecticut Polish American Archives has collected many ephemeral publications that are placed in its vertical file. Materials

include anniversary booklets, convention materials, programs of concerts, celebrations, reunions, dedications, dinners, balls, and testimonials. These publications may contain historical essays, photographs, and membership lists. A significant part of many of these pamphlets is devoted to advertisements by local businesses and prominent members of the community along with lists of contributors, donors, committee members, and congratulatory letters.

• Veterans History Project• This project collects oral histories along with war documents from American veterans and the civilians who actively supported them during World Wars I and II,

the Korean War, the Vietnam Conflict, the Persian Gulf War, and the Afghanistan and Iraq Conflicts. The Veterans History Project is sponsored by the Center for Public Policy and Social Research and the Burritt Library at Central Connecticut State University in partnership with the American Folklife Center, Library of Congress. The materials in this collection add a human face to the challenges, triumphs and tragedies of war and serve as teaching and research tools for the general public, scholars, faculty and students worldwide.
