Information in quotes was taken from Ann Scheppke's post on Libs-Or. The website "is the culmination of more than two years' work by staff at the University of Oregon Libraries, in collaboration with the Library of Congress, the National Endowment for the Humanities, and a number of state agencies and stakeholders" and was partially funded by an LSTA grant. Users have access to "historical materials originally published by Oregon journalists between 1846 and 1922. The website includes more than 180,000 pages of digital content drawn from historic newspapers that include the Salem Capital Journal and the Portland Oregonian." K12 lesson plans are available, although that section is still being developed.
