But thanks to Persinette in the Tower I have just discovered you can also read the full text online!
Here is a link to the translation by J.R. Planche, and here is a link to download the translation by Ernest Dowson. Dowson is the one who translates the Beast as (correctly) asking Beauty to sleep with him, not to marry him, which clearly has different implications (I've written about this before). The great thing about the Surlalune collection is that Heidi Anne Heiner included both translations for comparison, and in many ways print is easier to read and flip through than online, but I really wish I had known about this link a few years ago when I first started searching for BATB history!
