I like some of the later albums a lot too, such as "Salute" and "East of Midnight". I agree with all the others people have mentioned. Every one of them is great.

Cluin, I think I have one of the Lightfoot Anthologies you mentioned, but it's got a brown cover. The sheet music in songbooks is often printed out in the wrong key (from a guitar point of view).

You can surely find used copies of those songbooks at some place like Amazon.com or Ebay. Try it and see.
