Web site has been created to collect documents, letters, photographs, and histories of the camp and share them in an online exhibition. Materials from November 1938 through 1942 are being sought. The creators of the site plan to donate the collected materials in 2019, the 80th anniversary of the camp's establishment, to an appropriate institution for permanent preservation. A form is available if you have anything you can contribute to this memorial. If you can identify anyone in the photos that are already posted on the site, that information is also welcome.
The Boston Public Library has a project to transcribe its significant Anti-Slavery Manuscript collection. Many, many volunteers are needed to help with the approximately 40,000 items. The goal is to have everything transcribed iinto searchable text to assist researchers of all types. The transcription site was created and is hosted by Zooniverse, a common platform for this type of work. More information on the project and how to sign up is available here.
crowdsourced transcription projects on its own site that need volunteers. Current projects shown are "Family Life in the Midwest", "U.S. Western Expansion", and "American Indian History." Earlier this year a collection of Continental Army clothing receipts during the American Revolution was being worked on, but perhaps it has been completed, as it does not currently appear on the site.
Unfortunately, this one isn't about volunteering as much as it is about providing information. A funeral home in Montrose, Colorado was shut down in February 2018, and the FBI is requesting that people report their experiences with it. An article goes into some detail about the investigation, and a link to an online questionnaire is provided.
