The integration of the computer into an everyday home brought upon a big change in the lives of people. I put that the computer enhances literature distribution, because files can be transferred via internet to anywhere on the planet that has access. This in turn allows the distribution of literature to flourish because it does not have to be recreated every time it is needed in another place at the same time. The copy and paste format allows us to throw out the printing press together and replace it with a printer. This is why I placed the printing press as something the computer has made obsolete. 

Then for something the computer reversed, libraries are just aisles and aisles of books, other than the computers of course, and are really not needed when presented with all the wonders of the computer. The library could be just a bunch of screens, but it is supposed to promote literature and most of yesterdays literature is not digital. Therefore it has reversed the power of the computer, by letting people cling on to the old fashioned forms of paper and ink.

Lastly, for something the computer retrieves I chose locality. Once someone grasps the new concept of online communication, they usually then try to find their part in it. For example, Bob likes Heavy Metal but none of his local friends do. However, Bob created an online forum that is dedicated to other Heavy Metal listeners in his area. This in turn allows Bob to find more people like him, thus promoting Heavy Metal in his area.
