Section 01 of the register
Braille
Six raised dots in two columns give sixty-three usable combinations. Everything after that — contractions, separate codes for music and mathematics, the weight of the paper, the number of volumes — is production, and most of it is still done by hand.
- What it holds
- The exact text, its spelling and its print page references, read by touch with no device required.
- What it does not
- Bulk. One print volume becomes several, and anything laid out in two dimensions survives only as a translation.
