I'd like to include the guitar chords, where available, for the camp songs on the site I'm bringing back from the dead, but since I don't play guitar, I'm completely reliant on the wisdom and skills of others.

And that's where my question lies. If, for example, I get the chords from someone on Mudcat, do I credit that person? (and how, if they just signed "Guest" or got it from "somewhere online"?) What if I find the same chords on several different songbook sites? Proper attribution is important to me, but do the compilers of guitar chords get credit for them? (more relevant for songs whose origins are unknown or which were not guitar songs in the first place) How do I explain where I got the chords from? Do I need to?

Thanks in advance for your thoughts.
