I don't know them all, an but here are the ones I know.
The secret diary of Adrian Mole aged 13 and 3/4, The growing
pains of Adrian Mole, Adrian Mole: The cappuccino years, Adrian
Mole: From Major to Minor, and Adrian Mole and the weapons of mass
destruction.
They're not actually in this order, and that's not all of them,
but I hope I helped.
