Since the early days of the church, talks given by leaders (especially those given in the church's biannual general conference meetings) have been recorded and widely distributed in written format. A digitized collection of these talks dating back to 1971 is available on the churchofjesuschrist.org website, and talks dating back to the 19th century are available in printed format through various university and community libraries. In recent years, the LDS Church and BYU have also made audio and video versions of selected talks freely available on their websites.
