Introduction

Our objective is to integrate heterogeneous data sources in a virtual observatory and provide access to temporal, spatial and contextual dimensions of the underlying large volume of data.

The project consists of two parts: scientific and educational.

• Scientific: part of our broader interest in manipulation and image processing of terabytes of data (historical papers, geographical maps etc.). Process large volume of historical paper documents.
• Educational: web-based accessibility of Lincoln’s writings for scholars, students and public. The system combines already traditional learning (e.g. Google Maps); interactive learning by querying data content, and exploratory and forensic studies about characteristics of historical documents and their relationship to historical events.
