sometimes #lcsh uses a parenthetical qualifier after a topical term, when a term has very different meanings in different contexts

some things in #lcsh do not makes sense. Like instead of "Public policy" you are supposed to use "Political planning". WTF and why?

nowhere does assigning #LCSH feel more like engaging in some weird exercise in steampunkery than when cataloging contemporary books on video games and game studies. LCSH is a good 20 years? behind on the vocabulary

I just created an #LCSH proposal for “genderqueer people” in the system. I have no idea if it will be accepted, but to have the honor to create this for my own identity and more importantly for those who identify as GQ too… words fail. #cataloging #genderqueer

Does anyone have a snapshot of #LCSH in some #RDF serialization from before 14 March 2025? I would love to have an archive copy of it before the vandalism of the terms for "Mexico, Gulf of" and "Mount Denali".

We're still looking for volunteers for a working group on local authorities to address the recent #LCSH changes to Gulf of Mexico and Mount Denali. The working group aims to provide guidance on how libraries can either change their subject display or create local authorities #critcat

Scan of a letter from Sandy Berman to The Policy, Training, and Cooperative Programs Division of the Library of Congress. It reads:

Policy, Training, and Cooperative Programs Division
Library of Congress
Washington, DC 20540-4305

Dear Colleagues,

BRAVO! Your recent conversion of DENALI, MOUNT (ALASKA) and
MEXICO, GULF OF to MCKINLEY, MOUNT (ALASKA) and AMERICA, GULF OF, respectively, as both primary and subheadings was breathtakingly thorough and detailed. You are masters of your craft.
Alas, you are also willful handmaidens of chauvinism, ethnocentrism
and fascism. Also: Trumpism.

Many weeks ago I expressed the hope that LC would resist the
temptation to implement this palpably capricious, arbitrary, and 
baseless name-charging. That admonition appears to have gone unheeded.

Our President has no authority to wantonly replace the name for
international waters that abut more countries than our own.
Beyond that, the Gulf of Mexico has been so known since about
the 16th Century. Its renaming, totally rejected by neighboring
Mexico, smacks of arrogant linguistic imperialism.

It seems the whole state of Alaska prefers the Athabascan place-
name, Denali, to McKinley, a U.S. President associated with American
expansion who never set foot in Alaska. The widely-unwanted name change is an affront to Alaska's indigenous population, as well as
its state legislature and two Republican senators.

Although LC has now fully demonstrated its lock-step deference to
bigoted, unjustified authority, I hope American librarians will muster the moral and intellectual strength. to ignore its dismal example. 

Sorrowfully, 

[large, sprawling, angry signature]

Here's a banger from Sandy Berman about the #lcsh changes from Mount Denali to Mount McKinley and Gulf of Mexico to Gulf of America (and The Policy, Training, and Cooperative Programs Division of the Library of Congress being "handmaidens to chauvinism, ethnocentrism and fascism."). 📚

Anticipatory Obedience at the Library of Congress - ACRLog On February 18, the Library of Congress (LC) sent an email announcement through its regular channels about a special list of revisions in the Library of Congress Subject Headings (LCSH). This list con...

My first post as a regular contributor to ACRLog is about LC not only implementing the changes to "Gulf of America" and "Mount McKinley," but *fast-tracking* those changes. acrlog.org/2025/03/28/a... #critcat #LCSH

Monthly List 12 LCSH 2 (2025)Library of Congress Subject Headings (2025)

In unsurprising news, tentative list 12a for #LCSH just published: classweb.org/approved-sub... and the headings are now officially "America, Gulf of" and "McKinley, Mount (Alaska)."

So now the workarounds can begin #critcat

So I guess I need to spend time next week creating and documenting local cross references on authority records because I will not institute the #LCSH changes for: Denali, Mount (Alaska) and: Mexico, Gulf of with all their associated headings.

I will not comply.

The courage will be shown by individual libraries who will continue to use "Gulf of Mexico" and "Mount Denali" in our catalogs.

Just like when LC cowardly revised the #LCSH to "Illegal immigration" in 2021, the onus will be on every library *except* LC to do the right thing. #critcat

Not good enough Judy Cannan. Blindly pointing to the rules in not a good enough response. #LCSH

Comments sent to #LC re: #GulfOfMexico and #MountDenali #LCSH proposals. Started each comment with the lack of literary warrant followed by very brief reasoning, followed by action to be taken (Denali: none; Gulf: see from). #cataloging #libraries

I can't tell anyone what to do about these #lcsh changes but before you even look to see how many records need changing consider whether that is complying in advance #tcmmf

Also encourage people to email LC to oppose this proposed revision, which was announced a few hours ago (with comments deadline of today 😡).

Your email can be short (1-3 sentences) and can focus on impact to your patrons. #critcat #LCSH #cataloging 📚

news about changes to #LCSH are disappointing to say the least but let's all extend our empathy to the catalogers working there

sigh #lcsh will almost certainly have to update its headings for Gulf of Mexico because LC is a government agency

Cataloging friends, consider cueing up a local authority record for "Gulf of Mexico" for when the #LCSH is changed. If you're in a consortium, start those discussions now. #critcat
