The AGS Library is in the process of "recataloging" materials from the rare room. Items are cataloged in detail using a card catalog but now librarians are getting everything entered into the online catalog. As part of this process of shifting and reshelving materials, http://www.flickr.com/photos/agslibrary/sets/72157629495808927/, a rolled map was discovered. Faculty at UW Milwaukee, Marquette University and the Universidad Nacional Autónoma de México have determined that the item is a 300 year old Mexican codice.
