The opening pages say this version is lightly edited for modern readers. Is there a way to determine what edits were made?

My first Lovecraft book was At the Mountains of Madness, which turned me off slightly because of how dense the verbiage was. This book was completely different. Very accessible writing style that painted pictures beautifully. I’d highly recommend this book to anyone

Gotta give some advice though, the people of dunwich’s accents are truly something else… just try to translate it as you read into something you understand and it’ll be a smooth read
