Advice needed - How to digitise periodicals

I work for a local museum in New Zealand. We many periodicals and books we would like to record onto a searchable digital database. We are looking for tips from people who have done this before - is an excel sheet a good system to record location etc? We would also like to know whether there is an easy way to digitise the actual content from periodicals etc without scanning page-by-page on a home-type scanner. Is there equipment available that can scan a whole magazine easily? Are there any companies offering a digitisation service?
