Hi, I am new here and to Vegas editing software in general. Can someone point out the best way of teaching myself Vegas editing. Is there a pdf I can download or training discs I can get? Thanks
Youtube is a fantastic resource for learning VEGAS (even if the tutorial is for an older version, it'll still apply in 20), there is also a tutorial section in this forum, VEGAS Hub inside of VEGAS Pro 20 also has some training resources, and you can always ask us any questions any of those things doesn't already answer for you.
Vegas Pro has a YouTube channel with lots of excellent tutorials: https://www.youtube.com/@VEGASCreativeSoftware
A very good basic intro to Vegas Pro was created some 3 years ago which is equally in most respects to the current Vegas Pro 20: 
In the 2020s, training discs (unfortunately or not) are a long-gone memory from the dial-up internet era and not long years thereafter.
Even those these are not new, the BASICS are nowhere covered as well as does Andrew Devis in his 59 part series. Now, you don't need to watch all 59, and I'd say watch a few of these from #1 to 10, let's say, then look at the description titles to determine if there is some particular area of focus and watch those. Don't bypass some of the more current videos by others as well, (I can almost hear the carpies now -- sadly, there are a few of those lurking here; ignore them -- trying to be wise and advising against the "older" and less relevant series I'm suggesting, but it's absolutely NOT the case, these are still absolutely the best) especially on newer features, like color grading, but as far as the nuts and bolts, Devis is the man. Try it, you'll like it.

Thanks Seb-o, this looks like a great tutorial series. VEGAS hasn't changed much over time so I have no problem with using older tutorials- there are some from a decade ago that are still completely relevant.
There's a fairly large list of Vegas tutorials and resources here.
