The following excerpt is from the August 15, 2016 edition of mainebiz.biz:
The Maine State Library in Augusta has received a $275,000 federal grant from the National Endowment for the Humanities to digitize over 100,000 pages of historical Maine newspapers.
…
Any Maine newspaper printed prior to 1923 could be included in the project provided that the master microfilm is available for imaging. Newspapers printed between 1923 and 1962 may also be eligible for digitization if the publisher is willing to provide a waiver of copyright to permit the content to be imaged and shared.
