Determining the CODOC Year Code

The year of publication is rendered differently in a CODOC call number, depending on the era of the publication. Practice depends on which of three date ranges is involved:

1. Previous to 1900
2. 20th century
3. 21st centry [on on]

Material published in the 20th century uses the last two digits of the full date of publication.

Example:

69

Material published from 2000 on uses all four digits of the date.

Example:

2002

For material published prior to 1900 a letter is used to indicate the first 3 digits of the publication date, and the fourth digit of the date is the second character of the year code.

Example:

Year       1853
Year code  V3
