In the first volume, you will only include pages that are transcribed within that volume. The table of contents pages (which will later appear in future volumes) are accounted for in their respective volumes. So, they are ignored in volume 1.
Your page numbers in the first volume and on the title page will be something like: i-biv, xi-xx, and 1-…
In Volume 2, your page numbering will begin with v or whatever page from the TOC is in that volume.
Subsequent volumes will have the next applicable TOC page.
So when the transcription is complete, ALL the print pages will have been accounted for.
