The document summarizes strategies for engaging expert crowds in annotation projects at museums. It discusses how to bridge enthusiasts' interests with museum needs, learn from unexpected crowd contributions, structure annotations with standards to aid experts, adapt to different types of experts, and engage and reward experts by combining work with pleasure. Key strategies include linking data to different languages, scientific and common names, and tailored vocabularies; profiling experts; finding gaps experts can fill; and gamifying tasks around domains like art, history, and birds.
