Once I have their ratios, I can now go back apply it for each season relative to today's league averages to get a Normalized DB. For example:

For his career 1901-1919, Player Y hits 1.4 times the league's batting average (.200) for the same time period. His .280 batting average normalized for today, where the league hits .265 would be: .371. I will do this 1.4 times for each individual season to get his hits total each year. I will do this for each of the stats in my batting file.

Hope this has helped.

Yep, that helps though I'm not sure that there was anything wrong with your previous methodology even though I don't know how you did it the first time. How did you do it?

You wouldn't happen to have a version of the old normalized db with stats for 2003 and 2004 would you?

And while I'm on the subject, why do you normalize the stats of current players. Shouldn't theirs stay the same if you're normalizing the db to today's standards?

No, because it will lead to a Lahman DB like ratings assignment which is not very good.

For the most part they do, but I am normalizing for an era, like 1997 to 2004, so today's players will have a slight adjustment. Not something that will be noticeable, i.e, Bonds in 2001 might have 71 or 75 HRs, instead of 73.

That's the one I looked at. Saw that Bonds had 71 instead of 73.

Which questions is this answering? The one about normalizing current players or the one about having 2003 and 2004 seasons?
