I have Steele and Harbison's "C: A Reference Manual", and _is_ very good, but probably not for _learning_ C. It does have very good explanations of some under-the-hood things that I haven't found elsewhere. It is also a good reference on the C std library, and does a good job at pointing out possible incompatibilities between ISO C, `traditional' C, and vendor-specific dialects. One of the things that I have always found confusing about C is that code can be written in several ways, depending on how lax the compiler is about enforcing different versions of the C standard.
