Is there an encyclopedia/list of common type classes in Haskell?

You might find "The Typeclassopedia" by Brent Yorgey (published in issue 13 of 'The Monad Reader ) helpful. From the abstract.

You might find "The Typeclassopedia" by Brent Yorgey (published in issue 13 of 'The Monad Reader') helpful. From the abstract: The standard Haskell libraries feature a number of type classes with algebraic or category-theoretic underpinnings. Becoming a fluent Haskell hacker requires intimate familiarity with them all, yet acquiring this familiarity often involves combing through a mountain of tutorials, blog posts, mailing list archives, and IRC logs.

The goal of this article is to serve as a starting point for the student of Haskell wishing to gain a יִrm grasp of its standard type classes. The essentials of each type class are introduced, with examples, commentary, and extensive references for further reading.

That's just what I was looking for. Thanks! – Tim Dumol Aug 28 '09 at 11:47 too bad pdfs don't support hyperlinking to sections, and google's html conversion doesn't show the diagrams.. – yairchu Aug 28 '09 at 12:23 Indeed.

I would have liked to open the "extensive references for further reading" in a new tab, without manually typing the URL into my browser. HTML++ – jrockway Aug 29 '09 at 0:35.

The Haskell 98 Report lists the predefined types and classes. If there's a library type you're interested in, you might want to start at the Haskell Library Contents or Index.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
