AIM 3-2-1 says that it is the responsibility of the pilot to insure
that ATC clearance or radio communication requirements are met prior
to entry into Class B, C, or D airspace; the Air Traffic Control
Handbook tells controllers that it is their responsibility to
coordinate the passage through that airspace of flights to which they
are providing services. Which is right??

Perhaps it's a matter of how one reads these things? For example, I
interpret your above statement as follows:

* The ATC handbook states that controllers must coordinate the passage
through their airspace.

* AIM 3-2-1 says that pilots must adhere to the instructions of ATC prior
to entry into Class B, C, D airspace.

In other words, pilots must follow the instructions they are given by ATC
before entering controlled airspace. Ergo, all pattern entry in controlled
airspace is determined by ATC. Where's the conflict?
