Episode list and cross reference?

The Show
1

I have many years of cartalk episodes downloaded. Many original episodes and many “best of” after Tom and Ray’s retirement.

I have a couple of questions that I’m hoping someone can answer:

  1. Are the best of shows one-for-one calls from an original show? In other words are all calls in a best of show the same as the calls in the original, or are the best of shows pieced together from different original shows?
  2. Does there exist a complete list of shows and cross reference of best of shows to the original shows (or show segments if the best of shows are pieced together)?

The reason I’m asking is that my collection is not complete from the early days. I figure at some point, I can quit downloading best of shows once I have a 100% collection of all calls.
