Anyone can participate in the LOC's Crowd project to transcribe documents in the WWII Rumor Project collection of notes and diaries. To get started simply go to the collection and choose a document. Your chosen document will appear on the left side of the screen and a field for writing your transcription appears on the right side of the screen. After you have completed your transcription it is submitted for peer review. A demonstration of the process is included in the video below.
Applications for Education
The By the People project is a good opportunity for high school students and some middle school students to learn about the role of information control in the United States during World War II while contributing to a national project. All of the collections in By the People do have timelines and some other resources that help to provide context for the documents that are in need of transcription.
The Smithsonian has a similar crowdsourcing project called Smithsonian Digital Volunteers.
