Early Conventions

The first ten years of SF conventions were a mixed bag, but even the largest was small by modern standards, and some were literally a few guys getting together for a day. But travel was difficult and the tendency of the time was to call nearly any planned get-together (of fans from different cities a "convention" (or a "conference." See the Fancyclopedia 2 article on “con” for the baroque early terminology).

Anglofan historians tend to take a hard line on what was or wasn’t a convention (they would omit the First Convention if they could). We are inclined to take the participants’ estimation, even if they declared conhood after the event.
