I am reading Sergey Fomin's and Nathan Reading's paper [Root Systems and Generalized Associahedra](https://arxiv.org/pdf/math/0505518.pdf). 


I need a good reference for associahedron of classical types. Besides, whether there are some conclusions for associahedron of exceptional types. 



Reference request: Associahedron
The original source would be Fomin-Zelevinsky, <https://arxiv.org/abs/hep-th/0111053>. Note that, for them, the "associahedron" is really just a fan (the normal fan to the simple polytope associahedron). The first realization of the associahedra as polytopes was given by Chapoton-Fomin-Zelevinsky, <https://arxiv.org/abs/math/0202004>. There has been subsequent work by others (including me).
