Aim is to ultimately supply the following info:
- campaign name
- campaign description
- rights holder
- work title
- work author
- a link to an edition cover
- a link to the campaign on unglue.it- the status, or progress of the ungluing
- when the campaign is finished
- whether the logged in user is a supporter
- whether the logged in user is currently supporting the campaign
Current implementation is to supply info for current book panel design
