As Nemicu pointed out, most of the spec information is extremely simple to look up via google if you know the model. As far as compilations of data:
Golfworks has a shaft rating system (shaft MPF) that gives a general comparison of the profiles and flexes. They're probably the best collection and the easiest to understand, plus they have most of the detailed specs on the sales pages. They won't have "made for" shaft models but they have a wide variety of aftermarket models.
Each shaft gets a 4 digit code. The first number is overall flex from 1-5, 5 being X stiff and 3 being regular in general terms. The second represents a few measurements including torque and weight to determine whether it's geared towards control or distance though most of the good quality shafts on the market fall under B or C. The third is trajectory, determined by bend point and profile which determines the amount of launch; this can be changed by tipping however so in the case of fairway woods it can be iffy. The final number is essentially weight and torque, and it supposedly refers to the directional tendency of the shaft; I don't buy into this one but the good shafts are almost all M or H, anything that adds distance or reduces slice under this system is basically a ladies or senior shaft.
This gives 4 areas of the shaft a flex number from 0-9, which can be very useful in determining profile if you understand shaft design well. It is based on data and not subjective so it's useful at least. Miyazaki shafts all use this method to rate their flex and profile. For example, my driver shaft is a 5689, meaning a stiff butt with an XX stiff tip which makes it low launching and stable while still feeling reasonably soft in the hands.
This site also does some very good testing but only covers a small number of models.
