Great to see all you new pre-service teachers here in the "The Student as Historian" group
When I'm not posting as a TPS Mentor, I have another project at Substack called "The Forgotten Files" Each week I publish fascinating historical images drawn from a wide variety of archives - including the LOC. All artifacts are in the public domain and have a link back to sources.
The subject matter varies and sadly Substack does not include any tagging tools. But the search engine works well. Subscriptions are free - you can get new docs directly to your mailbox
If you're looking for a quick lesson builder to use with the images use something from this flexible set of Historical Thinking Prompts from TPS Connect. (See below)
Engaging visual artifact + thinking prompt = a quick mini-lesson.
