Software as a service (SaaS) is one of the most-talked about trends in IT. Unlike traditional perpetual licensing model, software applications are sold on subscription bases and services are provided over web by the vendors. It is said that SaaS can make vendors to invest more on R&D than on marketing while offering its customers better quality software applications at lower costs. By empirically comparing vendors providing their software applications either by SaaS or by traditional perpetual licensing model, we examine whether or not SaaS really increases overall customer benefits in terms of cost efficiency, software quality, and customization. We show that SaaS may not provide better quality or cost efficient software applications than perpetual licensing does. Then we provide two practical tools which are useful for customers to evaluate whether SaaS is better than perpetual licensing for the purposes of software applications they want to adopt.

In the print world libraries have served as the archival repository for journals that they owned. In the age of digital information, however, with the licensing of electronic journals libraries purchase access to journal contents rather than paying for ownership. Libraries note the potential benefits of electronic journals, but also quake at the thought of inaccessible electronic journal contents caused by lack of preservation, changing technology, or publisher requirements. It is real that libraries have not yet stepped in to create archives of the electronic journals they are purchasing. In the digital environments, publishers, libraries, and other information providers are not the independent units that we used to be. It will take us all working together to solve the problem of preserving access to electronic journals. Thus, it is reasonable that a national library would be charge of making a comprehensive archiving policy on electronic journals, and that cooperative agreements of local libraries can help divide responsibility for different subject areas or materials.
