The purpose of this paper is to implement the internet-based geographic information service of a literature with the development of GIS and IT. For this, this research tried to implement the Google Mashup service by extracting geographic knowledge and thinking of Goethe with the case of the literature 'Italian Journey'. In order to do it, eight categories were applied to extract geographic knowledge and thinking in the Goethe's Italian Journey. Next, the extracted texts were applied to the point locations where Goethe visited or stayed in Italian Journey, and the related data such as pictures, illustration, and video were collected and hyperlinked. In the perspective of cartography, in addition to the basic maps and functions from Google Maps, additional GIS files for administrative boundary, river, and city were converted to KML, and imported and incorporated into Google Maps for map service, which might help to understand the Geothe's geographical description about climate, geomorphology, and urban landscape of visited regions. Through this case study, I found the efficiency of GIS and internet map service for literature.
