Like most such systems, it contains several groups of characters that may code for different things depending on the classification and need. The first of these is the class designation. These consist of a letter for the primary category, additional letters for a sub-category, and often a group of two letters or a letter and a numeral for specific subclassifications.

===Peoples Classifications===
Classificaiton Classification HP is subdivided by cultural groups, or "peoples". This subdivision is presently tentative, as there are as yet few volumes deserving. Class A7 in particular has very few volumes assigned at present. A goodly number of peoples could be identified and added, but at present the others remain in classification HP. It is also possible that this subdivision will be applied to GP if volumes warrant.
*A7 = Arabs
*1819
When on the rare occasions when more than one notable is born in the same year, more specific dates are used, the months padded to two digits:
*1819-05
=Third Line=
When an author has written multiple books in a single classification, a Cutter code is assigned to the title of the work. These generally omit articles (a, an, the, and their equivalents in other languages). When the first words are the same or permutations of the same root (as genealogic genealogy and genealogical), Cutters for additional significant words in the title are appended without a space.
=Subsequent Lines=
==Publication Date==
Publicaiton Publication dates are useful when multiple editions exist. The same format as for Date codes is used; no special marks are added for estimated or interpolated dates.
==Volume Number==
==Copy Number==
When multiple copies are held, the numers numbers are shown as "c.1", "c.2", etc. Deaccessioning may cause some copies to be missing; it is not anticipated that remaining copies will be renumbered.
