I teach an Online Office Tools class for local organizations, and I always show Google Docs because most people already have Google accounts. At the end I always tell people that they should try Zoho when they go home because it has many more tools. Today I found out that you can login to Zoho with your Google (or Yahoo) ID. What a great idea!!
These online office tools are great for libraries because they're free to use and accessible from any computer with access to the Internet. I highly recommend teaching patrons about these tools to eliminate the cost of licenses for public PCs - it's also very handy for those working in virtual offices.
