What is missing in the TPB versions?

[Da Letter Jay]

I have never even read through, much less owned a single issue from Season Eight. Right now, all I own are the first two TPB volumes (so I haven't read Issue #11 and up yet). On some sites, mainly Wikipedia, there are references to letters columns in the original issues which feature Q&A's, but they have been omitted from the versions I have. What else is missing in the TPB's?

And is there a way to read that info online without having to physically get the issues?

Thanks in advance.

As far as I know, the comic in its entirety, minus advertising and letters sections is reproduced in the TPB's. At least, I can't find anything deleted from the original story arc of "Fray" from the 8 issues to the TPB.

So there's no way to read the letters pages online?
