Why do we use LCSH? What are its benefits and limitations?

--- Ref pcc statement about unreliability of lcsh due to political influence, etc. — ---Also consider adding issues of LC headings when they are changed but still are under terms that are offensive/wrong. Example Sadomasochism is under the broader term Psychosexual disorders, so while that term is not added to a record by a cataloger, currently Primo is "enhancing" records in Hollis to display "other search terms" based on the subject trees and will show "Psychosexual disorders." See this record in Hollis as an example: http://id.lib.harvard.edu/alma/990077274030203941/catalog
Alternative vocabularies and thesauri

Homosaurus terms are NOT faceted, so you are only able to assign general headings using it. Because of this it is best to use this vocabulary as a supplement to the LCSH since it is more robust and faceted when you are looking for more complex structured headings with $$v $$x $$y and $$y $$z fields. In addition to terms related to gender and sexual orientation, the thesaurus has many terms related to sex and sexuality that are not represented in LCSH and are very useful for describing our more recent sex positive collections and materials. For example, there is no term in LC for Tantric sex, but there is one in the Homosaurus.

Within Harvard Library the SACO Diversity, Inclusion, Belonging, and Anti-Racism Task Group (SACO DIBAR Task Group) "is charged with reviewing controlled terms governed by the Library of Congress Subject Authority Cooperative Program (SACO) for possible revision in light of EDIBA principles." Their wiki page tracks headings under consideration and includes a form for staff to submit terms for the group to review, they ask for the following information with each submission: the existing term, a proposed preferred term, the MMS ID of the corresponding bibliographic record in Alma, and references to any related sources and/or justification/reasoning for the change.
