American Philosophical Society announces the launch of PAL, an innovative recommendation tool for research libraries
Philadelphia, Pennsylvania—April 3, 2017—The American Philosophical Society is pleased to announce the launch of PAL (People Also Liked), a circulation data-driven recommendation tool designed specifically for archives and manuscript repositories.
Similar to the customer recommendation tools used by major online commerce sites, like Amazon and Netflix, PAL helps scholars discover relevant manuscript collections based on request history and user interests. Researchers at the APS use it to sift through the 13 million pages of manuscripts held at the APS Library, including the Papers of Benjamin Franklin, the Journals of Lewis and Clark, and the papers of seven Nobel Laureates.
“We had compiled a lot of user data that we weren’t really using. We realized that new technology could harness this data and improve a fundamental job of librarianship: helping people find what they need,” Patrick Spero, Librarian of the American Philosophical Society, said.
The tool was developed by Scott Ziegler, Head of Technology at the Library, and Richard Shrake, a consulting software developer who specializes in library science. Designed to interact with the APS’s circulation system, AEON, PAL captures data, anonymizes it, categorizes it, and then matches past user behavior with the needs of new researchers.
“Unlike recommendation tools for books or movies, archival collections don’t have a simple one-to-one relation,” said Ziegler. “That is, a Benjamin Franklin letter, for example, doesn’t have a unique identifier. In contrast, a book has an ISBN number, a number that uniquely identifies it. In the world of archives and special collections, we always need to maintain the context of any single letter. The trick is to also generate recommendations for collections similar to one that contains the letter in question. This is what makes PAL distinctive. It’s the first tool that we know of to do this.”
After months of developing and testing, the Library launched PAL in January 2017. Ziegler and Shrake presented the tool at Code4Lib National Conference in Los Angeles in March and are forming partnerships with other libraries to enhance the system.
“We’ve heard from a number of libraries interested in PAL and how they can use it for their collections. We hope to continue to find colleagues who are willing to help us generalize the tool for wide use,” said Ziegler.
Designed specifically for manuscript collections, the APS Library plans to share their work with other libraries. PAL is part of the APS Library’s digital scholarship initiative, which includes the digitization of APS materials, support for digital scholarship, and the development of new tools.
About the American Philosophical Society:
The American Philosophical Society, the oldest learned society in the United States, was founded in 1743 by Benjamin Franklin for the purpose of “promoting useful knowledge.” In the 21st century the Society sustains this mission in three principal ways. It honors and engages distinguished scientists, humanists, social scientists, and leaders in civic and cultural affairs through elected membership and opportunities for interdisciplinary, intellectual fellowship, particularly in the semi-annual Meetings in Philadelphia.
It supports research and discovery through grants and fellowships, lectures, publications, prizes, exhibitions, and public education. It serves scholars through a research library of manuscripts and other collections internationally recognized for their enduring historic
value. The American Philosophical Society’s current activities reflect the founders’ spirit of inquiry, provide a forum for the free exchange of ideas, and convey the conviction of its members that intellectual dialogue and critical thought are inherently in the public interest.
