Slideshare is a website where you can share and find Powerpoint presentations and pdfs on just about any subject you have an interest it. It was voted one of the World’s Top Ten tools for education and e-learning.
I’ve been to the website on occasion, often times having been directed there when I was researching some topic. As I mentioned, you can find slides that people have uploaded on any topic imaginable.
Here’s one I found on ancient civilizations.
Here’s one on how to start becoming a vegetarian.
And here’s another on how to dress for success.
Like so much on the internet these days, you’ll probably have to dredge through a bit of dreck to get to the good stuff, but it’s up there. I may even, at some point. upload a slide presentation I have on how to use the tarot for writing fiction. 🙂
