Rubbish in = rubbish out When people are using #LLMs to search for information, the quality of the #metadata that describes information resources becomes more important than ever. If that metadata is itself AI-generated, with no or low human quality-control, we risk degradation of search & discovery

Terrific new article about how the idea of "neutrality" has been used for decades to deny the approval of #LCSH relating to marginalized people. Great description of how subject headings are created and how inordinate scrutiny is given to certain proposals in order to appear "unbiased." #critcat 📚

On National Indexing Day, we need to celebrate this intensely human publishing role, says our associate editor and non-fiction previewer Caroline Sanderson 👇 #BookSky

Practical steps can be made with incremental change over time - no need for huge system overhaul,but a need to apply open metadata licences support a linked open metadata environment & build a community that can share & support one another to prioritise open standards & open infrastructures #RLUK26

Open Metadata can help us to address the fragmentation inherent in the current ecosystem moving us towards a more open and collaborative discovery environment without duplication of effort - but this requires open workflows & guidance & community knowledge sharing #RLUK26

Open Metadata is openly licensed and reusable without restriction - it has interoperable standards that are accessible beyond local systems to ensure it is discoverable on the web #RLUK26

Interesting session on #openmetadata #openbibmetadata & #openinfras from @ellycope.bsky.social at #RLUK26 Conference #metadatamatters

#RLUK26 has been full of 'calls to arms' for action to address big issues facing academic and research libraries from supporting #diamondOA reinforcing #rightsretention and #copyright in the face of AI & now moving to #openmetadata #RLUK26

Happy National Indexing Day @indexers.bsky.social 🥳
