The Budapest Open Access Initiative declaration turned seven on February 14th.
Here's an excerpt from the Peter Suber's posting about the BOAI:
Released on February 14, 2002, the BOAI "statement of principle,…statement of strategy, and…statement of commitment" was the first to offer a public definition of OA, the first to use the term "open access", the first to call for OA journals and OA repositories as complementary strategies, the first to call for OA in all disciplines and countries, and the first to be accompanied by significant funding. A good number of OA projects were already under way, but the BOAI helped to catalyze the OA movement and give it energy, unity, and identity.
