For the right understanding of the present table or method of finding books (tabule seu repertorii), you must know that on the north side are ranged those books whereof the capital letters are black; on the south side those whereof the capital letters are red. All are set down in alphabetical order.
On each side the first desk (analogium) is marked by the letter A; the second by the letter B; [and so forth].
Each desk has four divisions, the first of which is marked by the letter a, the second by the letter b, the third by the letter c, the fourth by the letter d. The first book on the first shelf of the first desk is marked A. a. i; the second A. a. ii; [and so forth].
