Google Web-Fonts library now have move than 500 open source fonts. The term "open source" means that you are free to share, improve or customize them and use them in every way you want, privately or commercially - in print, on your computer, or in your websites.
For using these fonts locally in Microsoft Office applications like Word, PowerPoint etc, you need to download them in your computer. So, first head to google.com/webfonts in a new tab. Browse through the available fonts in the library. Add favorable one to your collection.

Embedding Fonts with the File
Now when we have done it on our local computer, this font will not work when you distribute the file among your friends. There is a way to embed fonts with the file so that it will automatically move with the file.
Go to Word Options and find the save tab (for Office 2007 and higher). Check the Embed fonts in the file option. This will allow other people to view and use the fonts, even if the fonts are not installed on their computer.
Now you can circulate your documents without worrying about fonts.
