Technically, the Sharingan can "record" every jutsu, it just can't "reproduce" some of them. Those would be other kekkei genkai, since the user doesn't have the genes necessary. I'm not sure how it works with hiden jutsu. While there are some hiden jutsu that requires other things to perform, like Aburame's kikaichu, or Kidomaru's extra arms, I'm not sure how it would work with say, Nara's shadow jutsu, or Yamanaka's mind jutsu. For nature transformation, Sharingan users can record jutsu from every nature transformation, they just need to be able to perform the specific nature transformation to reproduced the copied jutsu. Fourth databook listed Kakashi as being able to perform all basic nature transformations, including Yin Release and Yang Release.
