Scarecrow Wiki:Classification standards

This is what I'm working on presently. I'm researching Library of Congress. Thanks.

NACO - Name Authority Cooperative Program

 * NACO Resources & Forms
 * LC Authorities

SACO - Subject Authority Cooperative Program

 * Subject Lists (incl. LCSH)
 * Classification Lists (LCC)

Example
note: I add those Wikipedia article links which can be sought and found by entering the LC control no. into Wikipedia’s Search box note: then I add to Scarecrow Wiki Categories those Hierarchical Relationship: Broader Terms (BT) cross-references given in the LCSH PDFs, for instance here: “BT Gases, Rare,” which becomes Category:Rare gases - if LCSH lists any Associative Relationship: Related Terms (RT), then I create a See also subheading for those, at the bottom of the page

LC Classification PDF Schedule topic subclassification
Q Outline Science
 * QD Chemistry
 * QD146-197 Inorganic chemistry  Inorganic chemistry
 * 181.A-Z Special elements. By chemical symbol, A-Z
