I teach Power Point and sometimes I recommend that people see a lot of other people's presentations. This is a great way to learn and get different perspectives on the way to deliver a presentations. The only question is where can you see all of these examples? Well Google has a nice feature that allows you to search by the file type. In the search box, type in the words filetype:, and an extension like PPT. PPT is the extension for Power Point but there are many others like PDF or DOC. Now once you have all that in, type in the word to describe the search, like vacations. To give you an example click on the link to see a search for Power Points about libraries. Give it a try!
