Fans of the long-running Dilbert and Doonesbury comic strips can now enjoy anthologies of each on the Kindle Fire. 40: A Doonesbury Retrospective by Garry Trudeau and Dilbert 2.0 by Scott Adams are available now — the first time either collection has appeared in digital format. Both sets include full color copies of the strips, and each anthology is made up of four volumes costing $7.99 per volume for Dilbert and $9.99 for Doonesbury. Both comics support Kindle Panel View for browsing, though if you need a bit of extra help navigating though them, Dilbert will show you how it's done.
