The collection
In 1982, the Ohio History Connection (at that time the Ohio Historical Society) received the Albert J. Ewing Collection from a private collector• Over 5,000 glass plate negatives of various sizes• Still packed in original boxes in which Ewing bought his
undeveloped dry plates • Some identifying information• Images dated ca. 1896‐1912• Most locations are small towns in southern Ohio
and central West Virginia
Ohio History Connection
Glass plates were the first base for photographic negatives• In use roughly 1850‐1920• Both amateur and professional photographers
– Studio– Itinerant– Industrial
• OHC has numerous glass plate negatives collections– Can last for many years with careful and appropriate
handling and storage– High level of detail; they scan beautifully!

The collection
A selection of the original plates have been exhibited twice: • January 2013‐June 2014 at the Ohio History Center• November 2015‐Fall 2016 at the Campus Martius Museum in
Marietta
Over the past 8‐9 years, OHC has been working to digitize and make these images freely available online at OhioMemory.org
The images
Posed portraits of Appalachian residents • Material culture of the region on display• Livestock and family pets • Homes or businesses and personal property
Less formal portraits and photographs documenting daily life
Intimate moments, posthumous and memorial photographs
Built environment of the region: homes, farms, businesses, schools and towns
Remarkable representation of Appalachian life at the turn of the 20th century with a deep sense of place
The challenge:
Glass plates scratching scanner glass
Lesson?
Get creative!
The challenge:
Issues with image quality
Lesson?
Experiment—and build quality control into your workflow (early!)
The challenge:
Descriptive information to be captured at item level
Lesson?
Aim for efficiency when you can—but take your time when it matters
