I will reference two projects:
Siobhan Davies RePlay: The Archive of Siobhan Davies Dance 
This presentation from October 2011 gives a comprehensive background and context (YouTube link opens in a new tab, duration 27 mins).
Take a look at the Kitchens mentioned in the presentation as well as the Guest Scrapbooks to help you become a little more familiar with the site content and navigation.
Secondly, take a look at the MotionBank project and specifically the online scores site (the introductory video gives useful advice about system requirements and site navigation). Basically, lots of bandwidth, latest browsers, and beware institutional firewalls but have fun exploring the site!
