Go to Yahoo or Googles search engine and type "species name care sheet". For instance, "Corn Snake care sheet". Using quotes will narrow down junk sites, but it might also eliminate good sources of information. I wouldn't use them.

If you care to tell what species you are looking for, I'm sure someone around here keeps that species/knows of good care sheets.

Most sub-species have way different care. Take Old World Asians vs Corn Snakes. Keep a Cave Dweller (Elaphe taeniura ridleyi) as you would a Corn Snake (Elaphe guttata) and you'd have a dead snake in a week.
