Hello All: I have a quick question about ISBNs. If I'm looking for a version of Dracula with this ISBN: 9780743477367, and BookShare has a version of it with this ISBN 9780743493451, is it possible that the edition BookShare has is the electronic version? The reason I'm looking for a specific version is because the professor wants us to read the inttroduction in the book, which is meant to help in understanding and reading the book better. Thank you so much for your time and help.
