    Abstract
    This article explores the reasons why librarians should be at the heart of Internet site development. There are two distinct ways in which librarians can most effectively contribute to this medium. The first is by getting involved in information architecture. This new discipline requires skills such as expertise in search techniques and navigational logic, and generally involves the librarian working closely with graphic designers to create a firm foundation for the site. The second area is the role librarians can play in the structuring of the data which drives the site (data management).

    Abstract
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web

    Abstract
    Large information delivery systems of the future will be distributed, object-based systems. These systems will very likely be implemented with client/server architectures where special-purpose servers work together in a loosely coupled environment to deliver information to their clients. This information will include text and also other forms of data such as image, graphic or tabular data

    Abstract
    Public libraries in the USA are moving into graphic user interfaces for Internet access. This had led to problems caused by Internet pornography and the subsequent installation of filtering systems in either system wide or selected areas of the library. Gives examples of some of the scenarios that can arise which exemplify the reasons for filtering and the problems it can cause. Discusses how libraries can respond in order to ensure that filering does not degenerate into censorship

    Abstract
    Confirms the accuracy of a prediction 4 years ago that the CD-ROM graphic interfaces then available would be rivalled in online. Many Web based services now outperform CD-ROM models and magazine pages often look better on the Web than on CD-ROM. Desirable, but not widely available, is the facility to download data from CD-ROM databases. The best CD-ROM authority and retrieval software packages with impressible capabilities remain expensive but there are reasonably priced alternatives for Web publishing and database searching, many of which are derived from CD-ROM originals. A new software development which allows replication of Web sites on CD-ROM will feature in articles in future issues of 'Information today'

    Abstract
    Changes in the topography of the Web can be expressed in at least four ways: (1) more sites on more servers in more places, (2) more pages and objects added to existing sites and pages, (3) changes in traffic, and (4) modifications to existing text, graphic, and other Web objects. This article does not address the first three factors (more sites, more pages, more traffic) in the growth of the Web. It focuses instead on changes to an existing set of Web documents. The article documents changes to an aging set of Web pages, first identified and "collected" in December 1996 and followed weekly thereafter. Results are reported through February 2001. The article addresses two related phenomena: (1) the life cycle of Web objects, and (2) changes to Web objects. These data reaffirm that the half-life of a Web page is approximately 2 years. There is variation among Web pages by top-level domain and by page type (navigation, content). Web page content appears to stabilize over time; aging pages change less often than once they did

    Abstract
    Purpose - The purpose of this paper is to engage in a systematic analysis of academic research that relies on the collection and use of Twitter data, creating topology of Twitter research that details the disciplines and methods of analysis, amount of tweets and users under analysis, the methods used to collect Twitter data, and accounts of ethical considerations related to these projects. Design/methodology/approach - Content analysis of 382 academic publications from 2006 to 2012 that used Twitter as their primary platform for data collection and analysis. Findings - The analysis of over 380 scholarly publications utilizing Twitter data reveals noteworthy trends related to the growth of Twitter-based research overall, the disciplines engaged in such research, the methods of acquiring Twitter data for analysis, and emerging ethical considerations of such research. Research limitations/implications - The findings provide a benchmark analysis that must be updated with the continued growth of Twitter-based research. Originality/value - The research is the first full-text systematic analysis of Twitter-based research projects, focussing on the growth in discipline and methods as well as its ethical implications. It is of value for the broader research community currently engaged in social media-based research, and will prompt reflexive evaluation of what research is occurring, how it is occurring, what is being done with Twitter data, and how researchers are addressing the ethics of Twitter-based research.

    Abstract
    Libraries can add value to Internet resources by adding them to the library's catalogue in a manner consistent with the other resources held within the collection. Reports on OCLC studies into cataloguing Internet resources and accessing electronic periodicals. Existing retrieval methods on the Internet are limited because of shallow directory structures and idiosyncratic naming conventions. Catalogue entries for electronic resources need to provide a complete description of the access methodology if they are to satisfactorily connect remote users without the immediate possibility of backup from reference staff

    Abstract
    The use of codes and other methods of concealing the contents of messages is as old as recorded information. With the advent of computer communication, the need for a method of ensuring secure communication over insecure channels, such as the Internet, has seen an increased demand for good cryptography. However, the recent availability of public domain public key encryption software, such as Philip R. Zimmermann's Pretty Good privacy (PGP), has been seen by some as betraying the principles of security and has raised issues of national communication policy and personal privacy. In the USA, the government's Clipper encryption chip initiative sought to implement a key escrow system which would enable law enforcement agencies to wiretap all digital communication. Civil liberty opponents of key escrow systems argue that they will not affect criminals, and fear that they can only be made effective by banning the use of alternative encryption systems, such as PGP. Describes methods for obtaining and using PGP to encrypt and decrypt electronic mail messages

    Abstract
    Presents WebTagger, an implemented prototype of a personal book marking service that provides both individuals and groups with a customisable means of organizing and accessing Web-based information resources. The service enables users to supply feedback on the utility of these resources relative to their informatio needs, and provides dynamically updated ranking of resources based on incremental user feedback. Individuals may access the service from anywhere on the Internet and require no special software. The service simplifies the process of sharing URLs within groups, in comparison with manual methods involving email. The underlying bookmark organization scheme is more natural and flexible than current hierarchical schemes supported by the major Web browsers and enables rapid access to stored bookmarks

    Abstract
    Reviews the significant changes in information technology over the last 50 years and considers the many implications for information services. The Internet, global access to distributed information sources, and remote users all present challenges to would-be providers of information services. As resources proliferate, the information professional must develop new methods for locating and accessing them: reliance on publishers and reviews is no longer sufficient. Information service providers can now serve more diverse clienteles, but must be aware of the greater range of information needs and styles of information seeking. The continuing challenge is to harness the information technologies to meet these needs

    Abstract
    Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.

    Abstract
    The reader of a hypertext document in a web environment, if maximum use of the document is to be obtained, must visualize the overall structure of the paths through the document as well as the document space. Graphic visualization displays of this space, produced to assist in navigation, are classified into four groups, and Heo and Hirtle compare three of these classes as to their effectiveness. Distortion displays expand regions of interest while relatively diminishing the detail of the remaining regions. This technique will show both local detail and global structure. Zoom techniques use a series of increasingly focused displays of smaller and smaller areas, and can reduce cogitative overload, but do not provide an easy movement to other parts of the total space. Expanding outline displays use a tree structure to allow movement through a hierarchy of documents, but if the organization has a wide horizontal structure, or is not particularly hierarchical in nature such display can break down. Three dimensional layouts, which are not evaluated here, place objects by location in three space, providing more information and freedom. However, the space must be represented in two dimensions resulting in difficulty in visually judging depth, size and positioning. Ten students were assigned to each of eight groups composed of viewers of the three techniques and an unassisted control group using either a large (583 selected pages) or a small (50 selected pages) web space. Sets of 10 questions, which were designed to elicit the use of a visualization tool, were provided for each space. Accuracy and time spent were extracted from a log file. Users views were also surveyed after completion. ANOVA shows significant differences in accuracy and time based upon the visualization tool in use. A Tukey test shows zoom accuracy to be significantly less than expanding outline and zoom time to be significantly greater than both the outline and control groups. Size significantly affected accuracy and time, but had no interaction with tool type. While the expanding tool class out performed zoom and distortion, its performance was not significantly different from the control group.
