A conference slide asking "What is Digital Preservaton?" The slide answers with a definition from the DPC: "The series of managed activities necessary to ensure continued access to digital materials for as long as necessary." The slide annotates this definition: "managed activities": Multiple copies, Format normalization, Virus checks, Fixity checks, Metadata, Cybersecurity, Digitization, Web archiving, Policy "continued access": The overall goal is long-term access. "digital materials": Any digital file: websites, emails, photos, spreadsheets, etc. "as long as necessary": The digital lifecycle can include deaccessioning.

I really love this annotated definition of #digipres that Natasha Fisher (digital archivist at arquives.ca) gave at #c4l26.

In fact, I'm so fond of it that I've printed it out and put it on the bulletin board by my desk!

We didn't congratulate ourselves enough at #c4l26 on refusing to counter Carnegie Mellon kicking us out because our bursaries are called (and are) Diversity Scholarships. I don't mean it should have become a focus, but recognizing more how we insisted on our values may help the next time. #code4lib

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 […]

Slide-show slide with the following text: - What knowledge or skills are lost when we use Al to perform our own work and support the work of others? - In what ways are we undermining the capacity to engage in scholarship and conversations about cultural heritage? - How does Al usage contradict our institutional missions and values? - What legacy are we leaving for future library and archives workers, stewards, and patrons?

Amazing talk at #c4l26 by Yale’s Summer Shetenhelm on the ethics of AI within libraries

At my workplace, we do quick share-back presentations about conferences we attend. Every year, half my presentation is about what orgs and conferences could learn from #c4l26 by prioritizing accessibility. Also, it's volunteer run, supportive to new speakers, and not an association fundraiser.

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 […]

This was an outstanding example of, to paraphrase @thatandromeda.bsky.social, writing the manual you wish you had had. #c4l26

I'm staying out in west #philly for #c4l26 and can see why people love this city so much.

Nightingale explicates the Black press as infrastructure (a robust system with redundancies, distribution) and explains how digitization has the potential to support or obscure that infrastructure. 📚 #code4lib #c4l26

Brandon Nightengale “Archives are an engineered system that decide what persists.” He reminds us that systems are series of affirmative decisions by people about what’s important. 📚 #c4l26

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!
