Henry IV Part II, is not as exciting as part I, it lacks a lot of the content that helped move part I along (it has been said that perhaps it was simply written as a money maker as Part II was immensely successful following its first performance) but otherwise it is equally well constructed.
The edition offers the usual copious historical and contextual information in the introduction but as with many of the Oxford Shakespeare; it occasionally lacks explanations for what feels like vital vocabulary and phrases. The information that isn't provided is easily accessible online but when you don't want to be referring to the internet whilst trying to read the play, it can be a little irritating and certainly interrupts your flow. I find the Arden Shakespeare are much better for providing the right amount (concise) historical and lexical information underneath the main body of the text, so that you can quickly refer to it as you read, which is more suitable for the heavier, more demanding history plays.
