Here is another article. This one is from the journal, Partnership: The Canadian Journal of Library and Information Practice and Research.
From some of the abstract:
The Steacie Science and Engineering Library at York University hosted its first annual Steacie Library Dungeon Hackfest in February 2013. The purpose of a hackfest is to spend a day (or longer) using computer programming skills to collaborate on a particular software project and, hopefully, bring the project to reality. The project may be an app, widget, or website. It is evident that hackfests, as a form of engaged learning, help to reinforce the relevance of the library since it has implications for information literacy, open access, faculty liaison, and the changing perception of library as place. Twenty-five participants that included students, faculty, and staff hacked on Open York Data: York University’s openly accessible records and data such as course codes, lab stats of computers available in various libraries, subject headings, and research interests of faculty.
