Initial Findings, Thoughts & Implications
• Does it even matter that users seek content at a publisher platform over a
local platform?
• Should a local platform be transformed into something that competes with a
publisher/commercial platform? Or should it be transformed into something
that better serves the remaining users? Or should it just stay the same?
• What can be learned from the EJC to enhance other types of local platforms
being developed today (institutional repositories, digital archives, data
libraries)?
