This paper is a bit old but still very relevant:
An External Representation for the GHC Core Language http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.25.1755
Or: http://www.haskell.org/ghc/docs/papers/core.ps.gz Note that External Core, as specified in this paper, is similar to but not entirely the same as the version of Core that GHC prints out for debugging purposes. GHC 6.10 will be able to produce External Core with a flag again, and at that point Section 5.15 of the users' guide will point to a new version of the documentation -- so if you upgrade to 6.10 when it is released and are still poring over Core code then, be sure to get the new documentation.
