Research History
David Lewis published a book of philosophy in 1973 called "Counterfactuals" in which he discusses the possibility of alternate worlds. We would be interested in obtaining any cites from this book that indicate he used "counterfactual" to mean an alternate world or history.

We would like cites of any date from other sources.
