The amount of effort it takes to maintain and update fittings is overwhelming. And a lot of fits were obsolete, to be honest. The changes coming out from CCP
tend to be fairly consistent and constant and this means the meta is constantly changing. "Last month's flavour is now this month's garbage" if that makes sense.
No longer in the Uni but it could be possible that many of the fits were saved in Corp fittings in-game? Many of the current doctrinal fits are on the forums and I imagine in the corp fittings window in-game.
There are many sources of fits on the web as it is. ZKillboard
is a good source of fits. Keep in mind, just because something is killed doesn't mean it was a bad fit. There is also EVE Workbench
The real ticket is learning
to fit. Once you know the basics you can play around with the in-game fitting tool, or Pyfa out-of-game if you like, to tweak for what it is you're fitting to. And what fit works for one pilot may not work for another doing the exact same thing.
Uniwiki Fitting Guide
is where you would want to start.
