About the work

A closer look.

Send one sentence: the claim, and where you saw or heard it. I go to the earliest primary source I can reach — the dated document, the archive, the register, the recording — and tell you what it says, what each source is, and what I could not confirm. You get a written answer, one page, with every source listed and one included revision. If the record cannot settle it, I say so instead of guessing.

How I work: one sentence is enough to start. I read the source before I answer, and I cite every one I use. I mark what stays unverified instead of filling it in. One revision included. If a claim cannot be settled from the record, I say so.
