Victoria Van Hyning writes: “Online cultural heritage crowdsourcing invites people, usually volunteers, to enhance the descriptions of library, archive, and museum (LAM) items through tagging, transcription, and providing first-hand knowledge. Cultural heritage crowdsourcing has surged since 2015, when several tools and platforms became widely available. Crowdsourcing discussion platforms provide excellent opportunities for outreach, troubleshooting, and engagement between LAMs and participants. But these platforms can also be understood as spaces for conducting open reference services, and gathering information about what users need to know to engage with your collections online.”
