Actually this effort will not be necessary. Once I started in on it and begin looking at the source html I found that when one opens this link http://ebooks.adelaide.edu.au/i/ibsen/henrik/peer/ and examines the small navigation box at the upper right on the page, one option (the green [what is meant to be an e] symbol at the bottom is a link to download this as an epub. So this would seem to be a good source based on a preliminary look. Happy reading all.
