JSTOR has launched a new Labs team charged with partnering with the community to seek out new opportunities and refine and validate them through experimentation. The JSTOR Labs team has been using Flash Builds -- high-intensity, short-burst, user-driven development efforts -- in order to prototype new ideas and get to a user saying “Wow" in as little as a week. In this talk, I¹ll describe how we’ve done this, highlight the partnerships, skills, tools and content that help us innovate, and suggest ways that libraries can adopt these methods to support innovation and the digital humanities.
