SuDoc numbers are made up of the STEM (all the letters/numbers/punctuation BEFORE the colon) and the SUFFIX (everything that FOLLOWS the colon).
SuDoc classes are arranged alphabetically based on the leading letter(s) in the stem. SuDoc classes file alphabetically no matter how many letters are used (ex. L comes before LC; N comes before NAS which comes before NS).
The number in the stem between the period and colon is a whole number (ex. HS 1.2: comes before HS 1.15:).
Both before and after the colon, an empty space will file before a space that has a letter or number (i.e. “nothing” before “something”).
