Reading a Ledger's Totals Against Its Entries
Launch library · evergreen read

A ledger's running totals are a form of built in verification, since adding up the individual entries should, in principle, produce the total figure written at the bottom of the page, and any mismatch between the two is worth investigating rather than simply passing over in silence.
A discrepancy can point toward a simple arithmetic error made at the time, a missing entry never actually recorded, or in rarer cases something more deliberate, and distinguishing between these possibilities usually requires additional context beyond the ledger page itself to resolve with any real confidence.
Checking totals against entries is unglamorous, careful work, but it is exactly the kind of quiet verification that can either strengthen confidence in a source considerably or flag a genuine problem before it quietly finds its way into a finished piece, where it would be considerably harder to correct once it has already reached a wide readership.
