Library 2.0 is an international community of librarians who are interested in "the future of libraries in the digital age." Founded in 2006 by librarian and blogger Michael Casey, Library 2.0 has grown into a global organization that offers a number of professional development opportunities, including traditional conferences, virtual conferences, and webinars. Many of these virtual conferences and webinars have been recorded over the years, and visitors may view these recordings on the Library 2.0 YouTube Channel (link provided in the Archives tab). One such conference, Libraries as Classroom, provides multiple perspectives on how different kinds of library spaces can facilitate learning. Most of the conferences and trainings on Library 2.0 are free; those interested in joining the community will need to complete a free registration.
