I was cleaning out my old e mails and found: https://genealogybargains.s3.amazonaws.com/CHEAT+SHEET+Using+Yearbooks+for+Genealogy+Research.pdf
On the GenealogyBargains website, there is a whole page of free Cheat Sheets available. I didn’t see the Yearbooks one listed, but you can check out the many others at: https://genealogybargains.com/free-genealogy-cheat-sheets/
Thank you to Thomas MacEntee and GenealogyBargains for sharing these free cheat sheets with us!
