LingBuzz is an openly accessible repository of scholarly papers, discussions and other documents for “generative” linguistics. On top of its own papers, it also aggregates papers from the semantics archive, the OT archive, etc. making them all available and searchable in one place. The ultimate goal of lingBuzz is however larger than an archive of papers: It aims at gradually becoming both a community center for generative linguistics and an experiment in semi-automated article ranking.
