Today’s librarians recognize the importance of making sure library Web sites are easy to navigate, so users can find their way quickly to e-resources. But where’s a busy librarian to begin? This pamphlet offers a short set of simple-to-implement guidelines to help librarians design usable library Web sites. The guidelines are based on a survey of literature on library website design and usability testing, results of usability reviews conducted by Elsevier for library customers, and established best practices in website usability. Working with library website usability is at the core of the business of Elsevier’s User Centered Design Group. Whether we are reviewing usability of specific library Web sites to help individual customers, or assisting in design of electronic services and products offered by Elsevier, usability is our mantra.

Online chat solutions have been very popular long before AJAX was born. There are numerous reasons for this popularity, and you’re probably familiar with them if you’ve ever used an Internet Relay Chat (IRC) client, or an Instant Messenger (IM) program, or a Java chat applet. AJAX has pushed online chat solutions forward by making it easy to implement features that are causing trouble or are harder to implement with other technologies. First of all, an AJAX chat application inherits all the typical AJAX benefits, such as integration with existing browser features, and (if written well) cross-platform compatibility.

Web application technologies like PHP, CGI, Javascript, and Ajax have made it much easier for people to construct and deploy services on the Internet. Unfortunately, this has opened a wide avenue for new attacks since it is as easy to unintentionally introduce new vulnerabilities into web applications as it is to intentionally introduce new functionality.

There are hundreds of open source projects ranging from simple email software to publicly dedicated WWW servers and full operating systems. This article describes an online platform for educators with free open source educational systems including wikis, blogs, bulletin boards, Content/Course Management Systems, and MOOs, all open systems which are easily installed and managed. By setting up a content-based server, educators can save and archive their files online easily, and integrate their online resources without needing web design skill. With full control of these different educational tools, educators can form a collaborative learning community based on their teaching goals. Thus teachers and students can build an online community as partners. They can learn from and with others, share and try out web learning tools, distribute leadership and inspiration, and support and interact with others from all over the world.

Businesses currently face the daily challenge of managing content efficiently. These businesses are being flooded with information from web Content Management Systems (CMS) that present an all-too-simple picture. Instead, content management systems should solve the problem of turning content into information and information into knowledge.

CMS is defined as a generic term which refers to a wide range of processes that underpin the “next-generation” of medium to large-scale websites. Content management is a process which deals with the creation, storage, modification, retrieval and display of data or content.

Web services, an emerging paradigm for architecting and implementing business collaborations within and across organizational boundaries, are currently of interest to both software vendors and scientists. In this paradigm, the functionality provided by business applications is encapsulated within web services: software components described at a semantic level, which can be invoked by application programs or by other services through a stack of Internet standards including HTTP, XML, SOAP, WSDL and UDDI [3,18]. Once deployed, web services provided by various organizations can be inter-connected in order to implement business collaborations, leading to composite web services.
