Just as I was beginning to think about this 60th anniversary symposium, I stumbled across the “Index to v. 1-14 (1959-1973)” of the then-newsletter Extrapolation in the bookroom at ICFA, and this bibliography of roughly the first hundred articles published by the journal set me comparing the first hundred versus the most recent hundred, downloading the “From the Launching Pad” editorial columns from the early years, and taking a look at some of the pieces that called most loudly to my inner geek. What struck me most from the early years of Extrapolation were the vast white spaces on the genre map that confronted scholars. Latin Americanists can identify with this state of things, since that was the state of our region of the field a scant two decades ago.
