Charles mentioned this earlier, and then I received the following information from Terri Huntley, Historical Records Project Coordinator for the Washington State Digital Archives:
The Historical Records Project is designed for people to work from home using their computer/internet to transcribe or proofread selected documents (census, military, directories, birth, death, naturalization, and other materials). It isn't necessary to commit to specific hours since you work from your home donating your time at your convenience. The indexing efforts are posted online at the Washington State Digital Archives site: www.digitalarchives.wa.gov
Currently, many of the volunteers are transcribing many of the early Polk Directories that have been scanned at the Washington State Library. (We're working on early Seattle directories right now).
If you’re interested in volunteering, I need to know your spreadsheet preference: Works or Excel and your mailing address. Once we decide on a project to start on, I email a template and mail out paper copies along with postage paid return envelope. Once you have completed the project, you email the file back and return the paper copies in the envelope.
If you’re interested in volunteering, email Terri Huntley at: firstname.lastname@example.org
