samizdat: /sahm·iz·daht/, n.

[Russian, literally “self publishing”] The process of disseminating documentation via underground channels. Originally referred to underground duplication and distribution of banned books in the Soviet Union; now refers by obvious extension to any less-than-official promulgation of textual material, esp. rare, obsolete, or never-formally-published computer documentation. Samizdat is obviously much easier when one has access to high-bandwidth networks and high-quality laser printers. Note that samizdat is properly used only with respect to documents which contain needed information (see also hacker ethic) but which are for some reason otherwise unavailable, but not in the context of documents which are available through normal channels, for which unauthorized duplication would be unethical copyright violation. See Lions Book for a historical example.
