spinehide
/ˈspaɪnhaɪd/nounVerified NewThe second row of books packed behind the first on an overstuffed shelf, hidden from view and from memory.
The front row faces the room; the spinehide row faces the shelf back and is consulted only in emergencies. Double-stacking is shelving's densification move, quietly doubling the library while halving its visibility. Moving day reveals the population.
Etym. — spine + hide — the book spines literally hide; the term says what shelvers do.
