Library of Congress webinars are online-only instructional presentations consisting of audio, video, or audio-plus-slide-decks hosted on videoconferencing and online meeting platforms. Webinars can include workshops for educators, illustrated audio lectures, how-to guides to using services from the Library, subject-specific chat meetings and general question-and-answer sessions. They are often interactive and in these instances, recordings of Library webinars may include comments, questions and even presentations from attendees.
