2010 victories on Sandy Berman's latest Library of Congress Subject Heading personal scorecard (pdf) include:
Glee clubs
Hacktivism
Locavores (He proposed Local food movement)
Predatory lending
Show choirs
Workplace mobbing (Use for under Bullying in the workplace)
There are also four pages of yet to be implemented headings. Some that I could really use for zine cataloging are:
Anarcha-feminism
Bike mechanics
Fat acceptance movement
Freeganism
Genderqueers
Punk parenting
Sex workers
Sexism in punk culture (!!!)
Student anti-sweatshop movement
He also lists a bunch of genre terms for zines, which I'm all for. I'd want to caucus with the zine librarians posse on what those terms should be, though.
