"The Apollo Lunar Surface Journal is a record of the lunar surface operations conducted by the six pairs of astronauts who landed on the Moon from 1969 through 1972. The Journal is intended as a resource for anyone wanting to know what happened during the missions and why. It includes a corrected transcript of all recorded conversations between the lunar surface crews and Houston. The Journal also contains extensive, interwoven commentary by the Editor and by ten of the twelve moonwalking astronauts."
