On the Pathfinder SRD the lists as shown currently are, according to what I have read on the Paizo messageboards, not entirely accurate nor are all calculations done correctly for the various templates. I've also read in a few places that there are a bunch of types of, for example, elementals that can summoned.
What I would like to find a good link to and reference for is the full list of legal (ideally "legal for Pathfinder Society play") monsters that can be summoned with each fo the Summon Monster spells (I'm not playing a Druid so don't care as much about the Summon Nature's Ally spells). In the best case this resource would show all of the game stats as they would be used in gameplay during a Pathfinder Society game - so average HP, all bonuses calculated correctly etc. I don't have Augmented Summoning but it would be good to see the stats with Augmented Summoning (but also without). Calculating some bonuses and attack options can be tricky. In an even better case this resource would include full descriptions of all special attacks and feats each monster possesses (i.e. be a standalone resource useable even offline).
