I'd love too to collaborate with openlibrary, but at the beginning of our IEG project, me and Micru contacted them, in the person of Karen Coyle (User:Kcoyle),
a very famous and skilled metadata librarian who is somehow in charge of the project now.She told us that openlibrary is frozen, at the moment, and there is no staff nor funds to get that going.Openlibrary was previously funded but internet Archive.
If someone could build the tool you proposed, Luiz, that would be awesome, but I'm not a technical person and I'm not able to understnd if that is feasible or not.
