Code4lib isn’t entirely about code or libraries. It is a volunteer-driven collective of hackers, designers, architects, curators, catalogers, artists and instigators from around the world, who largely work for and with libraries, archives and museums on technology “stuff.” It started in the fall of 2003 as a mailing list when a group of library programmers decided to create an overarching community agnostic towards any particular language or technology.

Code4Lib is dedicated to providing a harassment-free community experience for everyone regardless of gender, sexual orientation, disability, physical appearance, body size, race, or religion. For more information, please see our emerging CodeofConduct4Lib.
