I've made a blog post out of my recent lightning talk at #c4l26, sharing some ideas I've been contemplating lately while in libraries and on trails.

The post includes my full text, links to sites and images shown in the talk, and some bonus links for context (including a book link that […]

Enjoyed hearing talks and meeting people at #c4l26 this year! Especially impressed to be meeting with a group which, as one participant put it, moved the whole conference across the state rather than compromise its values. (And for pulling that off on short notice, I'm willing to forgive any […]

Great to get to hear @natematias present (remotely) at #c4l26 on "Cultivating Knowledge in the Age of Agnotology".

(Agnotology is the study of ignorance, and apparently also of how ignorance is cultivated. As he points out, nowdays that's not just via suppressing knowledge, but also by […]

Yesterday the Post ran a story about the National Park Service censoring displays and exhibits critical of America's past. The NPS even has a database of what's being considered for erasure. I downloaded the 7GB database and turned it into a protest bot. Here's @nps-uncensored.bsky.social.

Attending Code4Lib remotely & I am *impressed* by how accessible they have made this conference. They had a venue canceled by CMU for politics, moved cities, & are still putting many orgs to shame by how inclusive it is to people with disabilities.

Until I visited the site yesterday, I'd missed that an appeals court had stayed the ordered restoration of the slavery exhibit at the President's House in Independence NHP in Philly. It's now only partially restored, with some community-added supplements […]

I'm seeing #c4l26 projected on the screen at the #Code4LIb conference in Philly, so I'm going to assume that #c4l26 is this conference's official hashtag for people posting on social media. Don't know how many attendees are posting in the fediverse, but hi to those who are here!

Bear with me if you can as I attempt to use HPV vaccines to demonstrate why many can’t see the danger of RFK Jr.

TLDR: Disease prevention takes time and discipline. Not discipline of an individual, but the ability to invest in public health when the benefits may not be immediately clear.

If you've realized that your AI-generated text is from a process designed to make it look just convincing enough to seem true without any assurance it actually is, the solution to your problem isn't "do another round of processing so it looks more convincing, but not any more true".

It does not take much imagination to consider how today's 5-4 SCOTUS ruling (that the Postal Service can't be sued for intentionally failing to deliver mail) could inspire attempts to suppress mail-in ballots: https://www.supremecourt.gov/opinions/25pdf/24-351_7648.pdf

Moved a little over 800 anonymous bulk Online Books submissions submitted in the last 24 days to low-priority bulk queue, or to the trash. They were from various IP addresses, but had similar characteristics, and a lot appeared to be redundant, rude, or mindless pattern-matching.

I see the phrase "purity culture" is now getting much the same skeptical treatment online as "virtue signaling" has.

Both phrases can identify a real problem, or be used to shut down attempts to live and promote one's values. One way to reduce confusion is to ask: Are you focusing on ensuring […]

@mattblaze True. But the long delay they imposed on stopping collection seems to largely have the effect of emboldening Trump to keep doing it as long as he and not someone they like less is in office. (Trump just predictably announced another statute he'll invoke for the next round of tariff […]

It's been a lot harder than I expected to find a definitely out-of-US-copyright edition of Arthur Ransome's _Swallows and Amazons_. The 1930 first edition sold slowly when it first came out, and as with many kids' books, copies were routinely trashed, and not often preserved by collectors. Later […]
