Works well but...

The program itself seems to work very well, quickly, and efficiently. However, after i waited a couple of hours to load and search my entire library to update via network, it seems that nothing has changed. I saved and opened itunes and nothing in there changed. The titles, songs, albums all stayed the same. Maybe there is a way to “update or refresh” itunes to reconize the new changes? I am very new to Mac and still a bit confused if anyone could lend me some advice on how to make itunes display the changes i would be greatful.
