Where is a good place to read about the properties of the length function on modules over a commutative ring (in particular, quotients of the ring)?
I'm looking mainly for basic properties.
I've tried looking in a number of general algebra books and commutative algebra books, but it seems that they only mention the definition along with the most basic of properties. I'd like something that goes into more depth, but so far have had no luck.
Is there a standard reference for this type of thing?
