This article looks at the access to geographic information through a review of information science theory and its application to the WWW. The two most common retrieval systems are information and data retrieval. A retrieval system has seven elements: retrieval models, indexing, match and retrieval, relevance, order, query languages and query specification. The goal of information retrieval is to match the user's needs to the information that is in the system. Retrieval of geographic information is a combination of both information and data retrieval. Aids to effective retrieval of geographic information are: query languages that employ icons and natural language, automatic indexing of geographic information, and standardization of geographic information. One area that has seen an explosion of geographic information retrieval systems (GIR's) is the World Wide Web (WWW). The final section of this article discusses how seven WWW GIR's solve the the problem of matching the user's information needs to the information in the system.

While intellectual property protections effectively frame digital humanities text mining as a field primarily for the study of the nineteenth century, the Internet offers an intriguing object of study for humanists working in later periods. As a complex data source, the World Wide Web presents its own methodological challenges for digital humanists, but lessons learned from projects studying large nineteenth century corpora offer helpful starting points. Complicating matters further, legal and ethical questions surrounding web scraping, or the practice of large scale data retrieval over the Internet, will require humanists to frame their research to distinguish it from commercial and malicious activities. This essay reviews relevant research in the digital humanities and new media studies in order to show how web scraping might contribute to humanities research questions. In addition to recommendations for addressing the complex concerns surrounding web scraping this essay also provides a basic overview of the process and some recommendations for resources.

My intent in this paper is to answer two questions: what were the principal events in the development of distributed mapping, and how should a narrative of its development be written? Distributed mapping is a mode of cartography arising from the convergence of the World Wide Web, GIS, and digital cartography. It marks a significant break with traditional cartography because (1) the set of rules that shape the map archive are being fundamentally altered; (2) the distributivity of spatial data, their analysis and visualization are at unprecedented levels; and (3) new forms of interactivity are emerging. After discussing some theoretical issues in the history of cartography, I locate the multiple origins of distributed mapping in the work on animated mapping during the quantitative revolution in geography and the availability of computing power from the 1960s through the 1980s. The technology is a series of non-deterministic negotiations with resistance leading to delays in implementation, back-tracking, and multiple avenues of exploration. The popularization of the World Wide Web during the latter part of the 1990s brought commercial attention to distributed mapping, not as cartography, but as support service for travel sales channels. Commercialization will detach distributed mapping from academic geography as it did with GIS before it. In conclusion, I outline the forseeable research issues for distributed mapping.
