I have gotten into the habit of always re-drawing the packages for myself as it is. So, you are saying that ther are no standards? Interestingly, when I look up TI parts for the ones I'm searching for today, the data sheets only show thru-hole package types, yet distributors keep quoting SOP's & SSOP's. This is definitely the most aggravating part of putting a PCB design together. Give me a nice technical problem that I know nothing about - before having me stuggle with this!
