NLM Video Search: A New Open-source Software Tool to Enhance Free Public Access to Historical Medical and Public Health Films (Luczak, Marill)
National Library of Medicine (NLM) Video Search is a new, unique software tool that offers rapid retrieval of Section 508-compliant historical medical and public health films created by the US government and in the public domain. NLM Video Search solves the challenging task of accurately searching digital videos with transcripts. In addition to offering a full-text search of a film’s transcript, the tool graphically displays where a search word or phrase occurs within the timeline of a film. Clicking the timeline results takes the user immediately to the appropriate portion of the film where the result appears. Digitized and coded using the H.264 standard to produce quality video in a small file, the video files are delivered progressively over HTTP, allowing rapid browsing within the film without latency. The initial group of historical films made accessible via NLM Video Search reveal how the potential of the film medium was studied and harnessed at critical times in American history. NLM Video Search software was recently named one of six winners by US Health and Human Services (HHS) Secretary Kathleen Sebelius in Round 3 of the latest HHSinnovates contest.

Leveraging the CONTENTdm API to Build a Dynamic Digital Collections Interface
(Joseph, Sprout)
The University of British Columbia Library has developed a PHP and JavaScript-based interface for presenting simple and compound digital objects managed in OCLC’s CONTENTdm to users in a new and dynamic manner. The interface was developed in response to a donor-funded project to digitize and provide access to 24 historical newspapers. The project coincided with the development of a new Digital Initiatives unit in the Library; colleagues from Digital Initiatives and Library Systems and Information Technology took the opportunity to work together to look at new ways of presenting CONTENTdm collections. The resulting discovery and presentation layer provides an interface to several collections of digitized historical newspapers, including metadata, image files, and optical character recognition text. This presentation layer extends the work of Simon Fraser University Library’s dmWebServices for CONTENTdm, and leverages native CONTENTdm image manipulation capabilities. The user interface provides full-text and date search, browsing by calendar, and a jQuery-based dynamic image viewer featuring paging, zooming, panning, search term highlighting, and a full-screen mode.
