Actually, it can be pretty hard... when I first started, I was all over the net, but the info I needed didn't turn up.
This surprises me, I have had good luck finding info on the net. Perhaps a lot has to do with what we are trying to find exactly. I know when I started researching the Twisted Tibia, I was searching for references to it in Peafowl, not much out there except "put them down". I had to kind of go sideways and start searching for it in broilers and emu's, then I started to get some decent info.
