We found 1 Reddit comments about Switzerland (Eyewitness Travel Guides). Here are the top ones, ranked by their Reddit score.
First the books:
Lonely Planet is great but the lack of pictures usually don't make them fun to read. I love the Eyewitness Travel Guides and the one from Switzerland is quite good.
A great book (and must read imho) is Swiss Watching by Diccon Bewes. He also has a blog with great insights of Swiss life/culture.
As for websites, myswitzerland.com does a decent job.
