A new indexing project of Irish records has been announced by Ancestry's World Archives Project team. It will see the Ireland Abstracts of Wills and Marriages collection indexed and made available free on Ancestry.
Despite its name, the collection also contains random instances of family trees and books, military records, invoices, memorial cards and transaction ledgers.
Ancestry's instructions to WAP indexers are thorough. You can read them on the WAP project page here.
