  Newby, G.B. ; Greenberg, J. ; Jones, P.: Open source software development and Lotka's law : bibliometric patterns in programming.
  In: Journal of the American Society for Information Science and technology. 54(2003) no.2, S.169-178.
  
  Abstract: Newby, Greenberg, and Jones analyze programming productivity of open source software by counting registered developers contributions found in the Linux Software Map and in Scourceforge. Using seven years of data from a subset of the Linux directory tree LSM data provided 4503 files with 3341 unique author names. The distribution follows Lotka's Law with an exponent of 2.82 as verified by the Kolmolgorov-Smirnov one sample goodness of fit test. Scourceforge data is broken into developers and administrators, but when both were used as authors the Lotka distribution exponent of 2.55 produces the lowest error. This would not be significant by the K-S test but the 3.54% maximum error would indicate a fit and calls into question the appropriateness of K-S for large populations of authors.

  Newby, G.B.: Cognitive space and information space.
  In: Journal of the American Society for Information Science and technology. 52(2001) no.12, S.1026-1048.
  
  Abstract: This article works towards realization of exosomatic memory for information systems. In exosomatic memory systems, the information spaces of systems will be consistent with the cognitive spaces of their human users. A method for measuring concept relations in human cognitive space is presented: the paired comparison survey with Principal Components Analysis. A study to measure the cognitive spaces of 16 research participants is presented. Items measured include relations among seven TREC topic statements as well as 17 concepts from the topic statements. A method for automatically generating information spaces from document collections is presented that uses term cooccurrence, eigensystems analysis, and Principal Components Analysis. The extent of similarity between the cognitive spaces and the information spaces, which were derived independently from each other, is measured. A strong similarity between the information spaces and the cognitive spaces are found, indicating that the methods described may have good utility for working towards information systems that operate as exosomatic memories

  Abstract: Prairienet is a free-net affiliated with the National Public Telecomputing Network, that has been in operation since Nov 93 in the USA. Examines the extent to which Prairienet is serving as a community resource for networked communication and information access through an anylsis of usage patterns and logs

  In: Annual review of information science and technology. 28(1993), S.187-229. Medford, NJ : Learned Information, 1993.
  
  Abstract: State of the art review of virtual reality techniques providing a logical progression from the foundation of virtual reality, current virtual reality technologies, and applications areas (medicine, art and entertainment, scientific analysis, business, and telerobotics). Speculates on the future of virtual reality as single area of study versus its fading into the background as specific applications go their own way, and virtual reality technologies become more common

  Newby, G.B.: ¬The maturation of norms for computer-mediated communication.
  In: Internet research. 3(1993) no.4, S.30-38.
  
  Abstract: Analyzes the communication norms of the major forms of computer-mediated communication. These forms include electronic mail, mailing lists, Usenet newsgroups, virtual environment, interactive massaging, and information services. Norms are the dominant standards for acceptable behaviour of a group of people. Each form of communication has a set of norms, which may be adjusted somewhat for a particular instance of communication for particular participants. new users of computer networks will find that the forms of the communication forums they may join are well established, but they will have the opportunity to create or participate in new forums where those norms may be somewhat different

  Newby, G.B.: ¬An investigation of the role of navigation for information retrieval.
  In: Proceedings of the 55th Annual Meeting of the American Society for Information Science, Pittsburgh, 26.-29.10.92. Ed.: D. Shaw. Medford, NJ : Learned Information Inc., 1992. S.20-25.
  
  Abstract: Proposes that navigation is a fundamental concept for information retrieval, with implications for information systems design. Develops this theme further in terms of: a brief review of a theoretical framework from which to consider navigation; describes a prototype retrieval environment built to investigate navigation; and presents the methodology and results of a user based evaluation of the navigation environment

  Abstract: Proposes navigation as a central concept for information systems. it formed the basis for information systems before the advent of computers and is again coming to the forefront of technological-based information systems design. Briefly describes a system under development which attempts to facilitate navigation for information retrieval

  Rosenbaum, H. ; Newby, G.B.: ¬An emerging form of human communication : computer networking.
  In: ASIS'90: Information in the year 2000, from research to applications. Proc. of the 53rd Annual Meeting of the American Society for Information Science, Toronto, Canada, 4.-8.11.1990. Ed. by Diana Henderson. Medford, NJ : Learned Information Inc., 1990. S.300-325.
  
  Abstract: Computer networking is an emerging form of communication which is having major societal and cultural impacts. We first focus on BITNET and INTERNET, which are parts of a worldwide computer network for researchers, academicians, and information professionals. Discusses the services and resources that are available on the network, describes ways that these services can be accessed and used, and suggests derictions for research that may be significant in understanding the impacts that computer mediated communication will have on social interaction, oprganisational structure and culture
