The Plains Indian Ledger Art Project (PILA) facilities the digitization of the unique genre of Plains drawing on paper created during the 1860-1900 period, in order to promote preservation, research, and public access. The project is located in the Department of Ethnic Studies at UC San Diego. This document describes the numerous aspects of the project. PILA is offered world-wide, without charge, as an educational resource for all.
Researchers estimate today that well over 200 books of Plains Indian ledger art still exist in institutional and private collections. They are extremely fragile, as the binding of the volumes and the paper were not intended to last centuries and cannot withstand frequent or intensive handling commonly associated research on visual objects of artistic and historical significance.
