This page offers information on paleography in many languages. Carla Rahn Phillips, who offered the Spanish Paleography workshop at the Newberry Library, compiled a detailed bibliography for those who want more manuals on the topic.
Created by the CUNY Dominican Studies Institute, this page offers several manuscripts with transcriptions. Scholars learning to work with manuscripts can practice their paleography skills.
This is a link to a digital copy of Jesús Muñoz y Rivero’s Manual de paleografía diplomática española delos siglos XII al XVII. This text includes example of different types of handwriting for practice with transcriptions. This link was included as a resource on a website developed from Dr. Martinez-Davila’s MOOC, Deciphering Secrets.
