For public domain books, I use Standard Ebooks, Project Gutenberg, and Internet Archive, generally in that order.

For copyrighted books, anywhere as long as it provides DRM‐free EPUB or PDF.

• Humble Bundle introduces a nice sale every few days. Key marker for DRM‐free: “Use on Any Device”. Representative recent purchases: complete Peanuts (42 vols.) for $25, complete Wheel of Time (17 vols.) for $18, complete Malazan (17 vols.) for $18, complete Lone Wolf and Cub (28 vols.) for $18… I check Humble pretty regularly now.

• Kobo Store. Key marker for DRM‐free: “Download options: EPUB 3 (DRM-Free)”.

• Google Play. Key marker for DRM‐free: “Content protection: This content is DRM free.”

• Barnes and Noble. Key marker for DRM‐free: “At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.”

Amazon rolled out DRM‐free ebooks (for some books) earlier this year, but at this point they’ve permanently lost my business.

Also, sites to purchase DRM‐free audiobooks:

• Libro.fm

• Downpour
