Online applications and tools

I am amazed at the variety of online applications available for free. I am sorry they weren't around a couple of years ago - maybe they were and I just wasn't aware -before my Library provided Microsoft Office products for customer use. However, I can still see a use for them as a service for Library customers. We charge for customers to use Microsoft Office products and it can work out quite expensive for customers having long assignments etc to type up. These free online products could be offered as an alternative to customers who cannot afford to pay.
