Many approaches have been pursued over the years to facilitate creating, organizing, and sharing collections of materials extracted from large information spaces. Little attention, in the context of hypertext collections, has been paid to the addition of new materials to these collections over time. Traditionally, human maintainers manually incorporate new(More)
A traditional library is a social place, however the social nature of the library is typically lost when the library goes digital. This paper argues social navigation, an important group of social information access techniques, could be used to replicate some social features of traditional libraries and to enhance the user experience. Using the case of(More)
Information on the Internet, especially blog content, changes rapidly. Users of information collections, such as the blogs hosted by, have little, if any, control over the content or frequency of these changes. However, it is important for users to be able to monitor content for deviations in the expected pattern of change. If a user is(More)
The Walden's Paths Project, as part of our philosophy of continual evaluation, seeks out user communities who may find our tool useful. However, our users, in the last few years, have reported a series of common issues and desired features. In order to support our users, we initiated a redesign of Walden's Paths to solve these problems and enable us to(More)
Web-based distributed collections often include links to documents that are expected to change frequently, such as blogs. The study reported here demonstrates that blog changes follow specific patterns. The results also illustrate the substantial role of standardized templates in blog pages. These results extend our earlier models that assess the(More)
While most digital collections have limited forms of change--primarily creation and deletion of additional resources--there exists a class of digital collections that undergoes additional kinds of change. These collections are made up of resources that are distributed across the Internet and brought together into a collection via hyperlinking. Resources in(More)
The Walden's Paths project is developing tools for leveraging student learning with the incredible amount of educational material on the Web. Specialized templates based on established educational frameworks, learning theories, or activities aid path authors in creating pedagogically sound paths by guiding them in collecting and structuring the information(More)
This paper presents a prototype of an authoring tool to allow users to collaboratively build, annotate, manage, share and reuse collections of distributed resources from the World Wide Web. This extends on the Walden's Path project's work to help educators bring resources found on the World Wide Web into a linear contextualized structure. The introduction(More)
We have been developing a system to support the management of collections of web-based resources called the Distributed Collection Manager (DCM). As work on DCM has progressed, questions about the characteristics of people's collections of web pages have arisen. Simultaneously, work in the area of social media technology has ignored investigating how people(More)
We have produced a system that automatically incorporates syndicated materials from sources including library acquisition records and online news sites to form growing hypertextual structures. This system enables users to create personal and shared collections built upon growing collections. It also seeks to empower users through the use of information(More)
