Secular Library Classification
The Dewey Decimal Classification (DDC), and the Library of Congress Classification (LCC) systems order subjects of knowledge based on principles for specific professions. The Dewey Decimal system organizes the subjects along the lines of how traditional primary education systems organize their curriculum - it is probably more suited for the school teachers, rather than the students. The Library of Congress Classification (LCC) system seems to organize subjects relative to the segments of time - past, present, and future. Although, proponents of the Library of Congress will argue the traditional description that it was developed for the legislators to reference - how else would you set it up for the legislators, other than a time reference of ideas?
The Secular Library Classification (SLC) system has a different approach, its principle is based on science - how would "science" organize the subjects of knowledge?
