thanks loads man!!!!
yeah, i was going to include the Phonautograph, but my teacher told me to narrow the theme a little bit and I decided to include the 20th century only.
Its about a 1000 words, not a lot really, but its like 70% of our year grade.
Thanks for the sites

, I'll check them later, but what I really need is books, they want me to get more stuff out of books than out of websites (i have no idea why though)
So, i'll just go to the library today and see if they have anything or not...
Know any good ones?
