JCDL

Welcome to the 13th ACM/IEEE Joint Conference on Digital Libraries -- JCDL 2013. It has been our pleasure to work with the Program Committee and with our colleagues on the Organizing Committee to build a program for this year's conference consistent with JCDL's long-standing reputation for high quality. JCDL remains the premier international forum for exploring research, practice, and social issues in digital libraries. The Program Committee has selected a diverse array of papers, panels, posters and demonstrations that illustrate both the breadth and depth of ongoing digital library scholarship. Some themes explored in this year's 13 sessions of full and short papers are familiar from JCDLs of the recent past (e.g., Digital Preservation, Metadata, Name Entity Extraction) and some themes are new this year, reflecting emerging and shifting foci of interest (e.g., Information Ranking, Information Clustering, Specialist DLs, Historical DLs).

Presentations of the papers included in this proceedings volume will be complemented by 36 posters and 10 demonstrations showcasing a broad range of innovative research and practical digital library applications. The extended abstracts for these Posters and Demonstrations are also included in this proceeding volume. This year's Poster & Demonstration Reception on the second evening of the main conference (Wednesday) will be preceded the ever-popular 'Minute-Madness' session. As in past years, reception attendees will vote to determine the winner of the Best Poster Award. Additionally this year, the Vannevar Bush Best Paper Award and the Best Student Paper Award will be presented at the Poster Reception. This year's program also includes three panel sessions. Wednesday's panel, chaired by Dan Cohen (Digital Public Library of America), will feature JCDL 2013 keynote speakers Jill Cousins, Cliff Lynch and David De Roure. Distinguished panels also have been assembled to discuss Managing Big Data and Big Metadata: Contributions from Digital Libraries (Tuesday) and to tackle the issues surrounding Volume, Variety, and Velocity: Big Data Collection and Curation in Cultural Heritage Repositories (Thursday).

Of course the essential pre-requisite for a conference of this quality and breadth is high quality submissions that span the full range of digital library scholarship. Again this year JCDL received a wealth of quality submissions. Each paper was read and rated by 3 reviewers. Each paper was then read by 2 additional meta-reviewers who reconciled first level reviews and formulated a recommendation for the Program Committee as a whole. During a day and a half in-person meeting in Chicago, the Program Committee made final selections. For this year's conference 28 of 95 full paper submissions (29%) and 22 of 72 short paper submissions (31%) were accepted. We wish to recognize the accomplishment of accepted paper authors and to acknowledge the many others who submitted strong paper proposals. An additional 13 papers submitted, a mix of both full and short, were converted to and accepted as Posters or Demonstrations on the advice of the Program Committee. Finally, we wish to thank Program Committee members for again meeting the challenge of reviewing a large number of papers both quickly and well; this conference would not be possible without their dedication and generous contribution of effort.
