The suite could read a cataloguing block and could ask a register, and
nothing showed the two together — which is the only way either is worth
acting on. A title page alone gives up a running head when the scan
starts late; an ISBN alone returns a confidently wrong book when the
catalogue has been carrying the wrong one for years.
The example's title comparison folds to letters and digits rather than
comparing strings. A register and a title page differ over case, over a
curly apostrophe against a straight one, and over whether the subtitle
counts as part of the title. An example that called those disagreements
would teach the wrong lesson, and did until it was fixed.
It runs on this library and finds both of the cases worth finding: a file
called Document5 by -ducati996 that both sources agree is Russell's
Problems of Philosophy, and a Pelikan whose stored ISBN belongs to a book
about sculpture.
The README now lists the forms it handles with an example of each, says that
where the italics sit is what decides whether they are the title or the
journal, and sets out what it refuses and why — scripture, Migne, a
contributor's biography, a note that only thanks people, a page footer.
Recipes gains "What a book leans on": one bibliography read, then the same
over a shelf, counted per citing book so a work cited forty times in one
bibliography still counts once. Every command was run — thirty converted
books gave 14,481 references, 10,536 naming a work, in about a second.
`records.md` now points at the five tools whose record shapes live in their
own pages rather than in `corpus-core`.
And pandoc escapes an underscore, so the rule of them that stands in for a
repeated author arrives as `\_\_\_\_\_` and was not being recognised.
