Song of Ice and Fire References other fiction

Whilst reading the Song of Ice and Fire I keep finding references to other fiction.

To start with there are frequent mentions of Snarks (Lewis Carrol).

The singer Marillion is a secondary reference to the Scimarillion.

In the second part of book 5 there is a discussion about ways to kill dragons that seems to refer to The Hobbit.

Also in book 5 part two one of the captured ships is renamed Shrike (Hyperion) .

A blackadder is used as a heraldic device.

There is a pythonesque reference ‘fart in the general direction’ when discussing the unsullied.

There are even start wars quotes: ‘you should let him win’ and ‘you are my only hope’.
