I had an issue and had to reinstall my OS. I was at 10.8.5. I have my original 10.5 disks and was able to install those, but I can't find my OSX 10.6 upgrade disk which is barring me from moving up to where I was. Does Apple keep track of my purchases of disks as a proof of my purchases? I need another DVD or a way to download that upgrade.

Sadly, as far as I know, Apple does not keep track of disc purchases. There are .iso versions out there, but I wouldnt recommend downloading them since you cant verify the source. Though I did find a archive of a disc from Apple here: https://archive.org/details/SnowLeopardInstall , it takes a bit of work burning it to a disc -- if you take this approach, be sure to click the .iso link on the right side.
If you want to buy another copy, this post has a technical run down: https://discussions.apple.com/thread/4471270?answerId=20150884022#20150884022
You can use the 10.6.3 retail disc on any Mac older than 10.6.3 but newer than January 7, 2006.
Lost my OS X 10.6 disk. Can I get another one?
