LISA 10 -- Library and Information Services in Astronomy. Report on the ESO workshop
The 10th LISA conference, held at ESO Chile in November 2025, explored how artificial intelligence, open access mandates, and expanding data archives are reshaping scholarly communication and redefining the role of librarians in astronomy.

Imagine the world of astronomy not just as a place of giant telescopes, but as a massive, bustling library where the books are actually star maps, data streams, and scientific papers. In November 2025, the librarians, data wizards, and scientists of this cosmic library gathered in Santiago, Chile, for their 10th big reunion, called LISA 10. Their mission? To figure out how to manage this exploding universe of information in an age where Artificial Intelligence (AI) is trying to read the books for them.
Here is the story of what they discovered, told simply.
The Robot Librarian vs. The Human Touch
The biggest buzz at the conference was about AI and Machine Learning. Think of AI as a super-fast robot librarian that can scan millions of images of the night sky in seconds, spotting patterns a human might miss. The papers showed that these robots are already helping curate data and find features in images.
However, the librarians were quick to put a guardrail on the robot. They argued that while AI is great at speed, it can't replace the human judgment needed for ethics and policy. They stressed that we need rules to guide these tools, ensuring they don't get too bossy or make mistakes. The paper suggests that AI is a powerful assistant, but it's not the boss yet.
The Universal Dictionary (UAT)
One of the tools they talked about is the Unified Astronomy Thesaurus (UAT). Imagine if every astronomer in the world spoke a slightly different dialect, making it hard to find the right book. The UAT is like a universal dictionary or a translator app that ensures everyone uses the same words for the same things. Even as robots start indexing books automatically, the group emphasized that we still need this shared dictionary to keep everything organized.
The Library is Evolving, Not Dying
A common fear is that in the digital age, libraries will vanish. The paper argues against this idea. Instead, the profession is evolving, not dying.
- Then: Librarians were like guardians of physical shelves, protecting old books.
- Now: They are becoming "connectors." They don't just hold the data; they link it together, make sure it's easy to find, and ensure it stays safe for the future.
The paper explicitly states that this isn't a sudden revolution where everything changes overnight. It's a steady evolution where librarians are applying their old-school skills (like caring for history and organizing) to new digital tools.
The Great Open Door
A huge theme was Open Science. Imagine a library where the doors are locked and you have to pay a fortune to enter. The astronomers are trying to kick those doors wide open.
- They discussed new ways to publish papers without charging authors fees, using models like "Subscribe to Open" (where libraries pay to keep the whole library open for everyone) or "overlay journals" that sit on top of free archives.
- They highlighted that while the idea of open access is popular, the reality is tricky. Bad policies can accidentally make things unfair. The paper suggests that for open science to work, we need a mix of good technology, fair rules, and human collaboration.
The Human Heart of the Machine
Despite all the talk of robots, data centers, and AI, the paper concludes with a very human message. Even with the most advanced digital infrastructure, the core of science is still defined by people.
- Librarians, data specialists, and researchers are working together to make sure the "findability, accessibility, interoperability, and reusability" (FAIR) of data works for everyone, not just the rich or the tech-savvy.
- The conference showed that while technology is changing fast, the need for human expertise to curate, connect, and care for knowledge is more important than ever.
The Cast of Characters
The gathering was a true global party.
- Who was there? 80 people attended, split almost evenly between those joining online (52.5%) and those in person (47.5%).
- Where from? They came from 16 countries, including Chile, Mexico, the US, Canada, and many European nations like Finland, France, and Germany, plus India and South Africa.
- Who spoke? The speakers were a diverse mix, with almost 70% being women and 30% men.
- The Vibe: It wasn't just serious talks. They visited a historic observatory on a hill in Santiago, saw a 12-inch telescope used for school kids, and enjoyed a dinner in a beautiful canyon.
The Future
The paper ends on a hopeful note. For the first time in the history of this conference series (which started in 1988), a group of colleagues volunteered to host the next event before the current one even finished. This shows that the community feels the meetings are vital.
In short, the paper suggests that while AI and big data are shaking up the library, the librarians are ready. They are swapping their dusting cloths for digital tools, but they are keeping their human hearts to ensure that the story of the universe remains open, fair, and accessible to everyone.
