At first, Teletype prepared its own manuals and then Bell Labs used them to prepare BSP-s (Bell System Practices) for the Bell System. About 1965 Teletype took over producing the BSP-s. Thenceforth a Teletype bulletin might be not much more than a cover and title page and a list of the BSP-s contained within, followed by the individual BSP-s.
