This is especially true if you consider all the "variations" - the second updated edition (global edition) which should rightfully be a third edition as it has two additional chapters and the two volume precursor texts: The Theory of Parsing, Translation, and Compiling Vol 1 & 2.

The first one was also perfectly sized and not making it a bulkier text like the current CS curriculum texts (CLRS, OS:Concepts, Korth's DBMS etc.)
