The website I enjoy visiting, related with my career in every aspects, is the one of the Precolumbian Art Museum of Santiago de Chile. I found the website because last year I had a subject called Prehistory, in wich I always had to do papers or homeworks about a specific subject, so the professors were very stricts with the bibliography or booklist. For this reason, we always had to search books or papers who were trustworthy and update, because we need to support our information. The thing is that in this museum there is a library, and the professor told us once that we could search for information and books in this place, so I entered in the website of the museum and I found a link to the library. In this website you can find whole books in line in PDF format, papers and bulletins of the museum that contains essays of differents anthropologists and archaelogist of Chile, and investigations of people who work in the museum. I don´t know if the website is amusing, but I enjoy visiting it, because you always find books and information about the expositions of the museum, you find information of different Latin American cultures, you can find videos, and a lot of information. I don't visit it very often, not because I don´t like to but because I never use internet very much, and because I usually don't have time to read anything but the readings of my subjects. Here is the link if you want to visit it...and if you do, I hope you enjoy it ;)
