Everyone experiences failure in their professional lives, but no one likes to talk about it. When we see failure approaching, we distance ourselves, avert our eyes, or – if we’re in its path – brace for the worst. But failure has intrinsic value and is an essential step on the path to professional and organizational success. And since it’s inevitable, we ought to learn how to look back on our failures to derive value from them, and how to look ahead so that our past failures can inform our future successes. Fail4Lib, now in its 8th year, is the perennial Code4Lib preconference dedicated to discussing and coming to terms with the failures that we all encounter in our professional lives. It is a safe space for us to explore failure, to talk about our own experiences with failure, and to encourage enlightened risk taking. The goal of Fail4Lib is for participants – and their organizations – to get better at failing gracefully, so that when we do fail, we do so in a way that moves us forward. This half-day preconference will consist of case studies, round-table discussions, and, for those interested in sharing, lightning talks on failures we’ve dealt with in our own work. Both newcomers and Fail4Lib veterans are welcome.
