I don't think there's a list of all previous nominations anywhere, that I know of anyway, but only books chosen as the selection for a month are ineligible to us, and there are lists of those.
For the lit club the complete list is
here. The other clubs each have complete lists here too, the older general club
here and the newer one
here.
However, they're all combined on a spreadsheet made by Dazrin (not sure if that's what you were referring to)
here. If you were referring to Dazrin's spreadsheets, the first default spreadsheet shown using most links to go there is the eligibility for the other club which is a little different from ours. That list is titled 'NLBC Eligibility Search'. I think the link I just gave automatically opens the second spreadsheet of Dazrin's, which is titled 'Complete List' (if not, you can click that title at the bottom of the spreadsheets to go to it). This is a combined list of all selections from the clubs here, and those are the ones that are ineligible for the lit club.
I'll try to update the first post in our welcome thread that has the more detailed guidelines with those links at some point, though aside from the selections list that post really needs a thorough going over altogether and I keep putting it off, heh.
