Open Office

My hermeneutics professor made his handouts available to the class already in a number of different file formats including one I had never heard of before: Open Office. Open Office is a free multilingual office suite and yes, you heard (or in this case read) that right, FREE. It is very similar to Microsoft Office and has a spreadsheet, word processor, powerpoint type presentation software, a database program and a graphics program. It also includes an equation editor. It reads and saves files in the Microsoft Office file format. You can download it here. I have tried it and it is pretty good.
