Locate the album you want to download, and make sure the site also allows you to download liner notes. Usually, this is in the form of a PDF.
Register for the download service. Often the sites that allow for the download of liner notes are record company specific, such as Universal Music. You will need to provide correct information concerning your name and address together with a valid form of online payment, usually a credit or debit account.
Install site-specific download software (optional). Sites such as Universal Music suggest this but they do not require it, and albums may be downloaded in compressed form as zip files.
Purchase the album using your registered details.
Download the liner notes or program booklet separately, if you can choose that option. If not, the liner notes will download automatically with your album.
