Michael Moorcock and James Cawthorn's Fantasy: The 100 Best Books is a terrific selection of classic (Western) fantasy. Organised chronologically, the authors' reviews are a combination of passionate and snarky. They make for very fun reading.
Below, I've pulled out all 100 books (100+, really, as there are a few series), and added links to free, legal sources where I could find them. (Publication dates and titles are as the authors had them. Where possible, I've left series together, even when it screws with chronology.)
