The Digital Public Library of America has released DLPA Strategic Plan 2015 through 2017.
Here's an excerpt:
We must, first and foremost, complete our hub network so that all collections and item types in America have an on-ramp to DPLA; fully build out our technology platform to ensure we have a solid foundation for many years to come and that anticipates further growth and diversification; and pursue an outreach plan that gets DPLA resources more widely into the hands of the global public, into education at all levels from kindergarten through graduate schools (with a special focus on underresourced organizations), and onto the screens of eager amateur and family historians and the developers who are creating the latest apps and websites.
