funkpower 6199fce251 colophon: file a book's printed subjects onto a shelf someone has ...

A cataloguing block states subjects in Library of Congress form, which
is precise, deep and no use for browsing. Real blocks from this library
read 'Political science – Early works to 1800' and 'English
literature—Middle English, 1100–1500—History and criticism'. Nobody has
a shelf called that.

--shelf takes the closed list the library is actually browsed by and
files the printed headings onto it, longest term first so a period of
thought does not collapse into its parent. Matching is on whole words
after folding punctuation away, because a cataloguing block separates
with em dashes, en dashes, full stops and plain hyphens, often three in
one heading, and OCR turns any of those into any other.

What matches nothing comes back under unshelved rather than being
dropped: a subject silently discarded is indistinguishable from a book
that printed none, and the difference is the whole value of reading the
block.
