First checks before you go further

Medical entries record fitness, treatment and hospital admissions in brief form, and they use medical shorthand of the period. Read them for dates and places, and do not turn a brief entry into a diagnosis.

Do not open five records at once. Open one, extract what it actually says, write it down with its reference, and only then open the next. Records disagree more often than stories do, and that is useful: a disagreement points to a transfer, a renumbering, or a variant spelling, each of which can be tested.

The order to work in

The steps below assume you have already fixed the person, the number, and the dates as far as you can. If you have not, do that first, and then return. Do not skip the step that checks the filters. It feels redundant when the filters seem obvious, and it is the step that catches wrong persons. Keep the timeline open beside you as you work, and add to it as you go, rather than reconstructing it at the end from memory. When working with family papers, note who holds the original and where it is kept. A paper you cannot relocate is a paper you cannot verify.

StepWhat to do
1List the forms in the file, and note any missing sheets or gaps first.
2Put the dated entries in date order, regardless of the order the sheets are filed in.
3Transcribe abbreviations and corrections exactly, before deciding what they mean.
4Add each interpreted entry to the timeline with its sheet reference, then decide the next record.

How to read this kind of entry

The order of sheets in a file is not always the order of events. Rebuild the date order yourself, and do not trust filing order to do it for you. When a file is thin, read it twice: once for what it says, and once for what kind of file it is. A thin file read as a thick one will be over-interpreted. Place names as written at the time may have changed, been misspelt, or referred to a camp rather than a town. A modern map alone will not settle them.

What are the common dead ends?

The most expensive dead end is a wrong person adopted early. Everything after that looks consistent, because it was built on the wrong foundation. When every avenue returns the same dead end, the dead end itself is information: it tells you where the record system stops, and that boundary is worth noting. Note dead ends in the timeline itself, with dates. A timeline that shows where the trail went cold is more honest, and more useful, than one that jumps the gap.

Where to go next from here

When the next step is unclear, reread the last dated entry in the timeline. The entry itself usually contains the question the next record must answer. Cross-check, rather than collect. One record confirmed by a second, independent record is worth more than five records that all repeat the same source.

Keep the person, the number and the dates together as you move to the next record, and re-check them on arrival. Filters drift when they are carried in memory. When the trail goes cold, note where, and when, it went cold. That note is the starting point of the next session, not a reason to stop.
