i tunes library

[oopsydoopsy]

Hi,
I have downloaded all of my purchases from i tunes onto my desktop computer. Is there any way I can share these or duplicate the library onto my laptop ?
I have backed up library onto an external hard drive.
Many thanks, all help appreciated.

On your laptop, open iTunes and then under store, go to Authorise this computer. When you sync ( or copy) your music to the iTunes on your laptop, they will play.
