If you are serious I can put you in touch with the current BMC crag athors. You do realise uncovering often is literal for Wildcat obscurities and that any formal clean-up needs to go through the access negotiators?
Even the 1970 guide Southern Limestone by Paul Nunn will have about 80% of the routes in it if you can pick one up from a second hand bookshop.
try Abe Books (www.abebooks.co.uk) and search for the book using the details above. I got 4 copies of the 1970 guide listed on abe books, between £7 and £11. Also got 6 copies of the 1987 guide listed on abe books (search Peak Limestone South by Geoff Milburn) in the price range £6 to £10. Please note that I am not a book salesman and having nothing to do with the companies listed above except that I have regularly bought books from them over a number of years.
Many of the routes won't need to be unearthed in a physical sense but do remember to take a helmet, less frequented limestone can have some loose bits! I love the place but then again I was one of the authors of the '87 guide. Winter is a good time at Wildcat, the veg is low, the weather is frequently quite a bit better in matlock compared to say hathersage, the crag is sheltered and catches any sun that is going - you can climb right through the winter if you don't mind a bit of discomfort in the finger department.
Become a trendsetter and help start the peak limestone revival, for too long far too many people have crowded onto a tiny proportion of the available rock in the peak - it is time to widen the field of view!
