@yofiel, You’ll find George MacDonald’s books digitized (transcribed, not just ORC’ed) at Project Gutenberg, and
digitized (scanned and/or ORC’ed) at Internet Archive. Links to these are over in this thread:
Many printed versions are available at Amazon and other book sellers, but it’s worth it to pay attention to the publisher. Many older works like his are published by low-quality fly-by-night places. Look for publishers like Penguin or Dover, etc.
