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)?
