"illegal and clandestine copying and sharing of literature," 1967, from Russian samizdat, literally "self-publishing," from sam "self" (see same) + izdatel'stvo "publishing" (from iz "from, out of," from PIE *eghs; see ex-; + dat' "to give," from PIE *do-; see date, n.1). Said to be a word-play on Gosizdat, the former state publishing house of the U.S.S.R. One who took part in it was a samizdatchik (plural samizdatchiki). Later and less common was tamizdat "writings published abroad and smuggled back into the U.S.S.R.," from tam "there."
