Melora of History of Hyrule has created a great website with scans of several of them to enjoy for free! Want even better news? Since she is missing a lot of Zelda comics and books, that I actually have, I will be providing full scans of the remainder of them for her to post!
In my books and comics section I'll be posting a link to all of the scans as well so you can read anything in my collection! ;)
So get reading now!
