The paper presents a model for academic libraries for the next 20 years. The parts of the model are: 1.) Complete the migration from print to electronic collections; 2.) Retire legacy print collections; 3.) Redevelop the library space; 4.) Reposition library and information tools, resources, and expertise, and 5.) Migrate the focus of collections from purchasing materials to curating content. The interactions of the parts of the model and organizational issues for implementation are explored.

Mechanical Turk aims to make accessing human intelligence simple, scalable, and cost-effective. Businesses or developers needing tasks done (called Human Intelligence Tasks or "HITs") can use the robust Mechanical Turk APIs to access thousands of high quality, low cost, global, on-demand workers -- and then programmatically integrate the results of that work directly into their business processes and systems. Mechanical Turk enables developers and businesses to achieve their goals more quickly and at a lower cost than was previously possible.
