Imagine having many of the office applications you use daily on your computer available online; all of your documents can be shared with collaborators around the world, day or night.
Co-authoring research papers or reports are much easier in this format because documents can be uploaded or saved back to your desktop in familiar .doc, .xls, .pdf, and .ppt formats!
Students pursuing guided independent study projects can do their work online, giving permission to faculty members to review the evolving project at any time, any stage, and make comments and recommend changes.
Other office suites are available online, such as http://zoho.com/ .
Another of the many useful Google tools is Google Scholar: http://scholar.google.com/ This tool not only filters returns for scholarly articles, but also digs out citations for those returns so those papers that cite the one selected can be reviewed.
