This page provides a simple search of the 'On This Day' pages based on subject terms I have added.
This list of terms isn't exhaustive, in order to keep the number manageable. I may add others or edit existing ones in the future.

The search allow you to select up to 4 terms, and results will be entries that have all the selected terms assigned. Be careful of selcting just a single general term, eg 'England'. Add additional terms to narrow the focus.
