Another discussion I found useful was in SICP: http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-17.html#%_sec_2.4.3 I really like the metaphor of method dispatch as a table with types in the columns and operations in the rows - then you can think of generic functions oo as being row-based, and class based oo as column-based.
