How #IndexDay started and how it ended.

It’s #IndexDay and I’m sat here reading every index in the house (as I do every day), and I’m rediscovering @baindex.org’s brilliantly amusing index to Alan Partridge’s ’Big Beacon’. Very funny!

Happy National Indexing Day @indexers.bsky.social #IndexDay
This year I have indexed texts on Buddhism, medieval Sri Lanka, performing arts, theatre, Carmelite history, Yoga, Spanish art and literature, and libraries, amongst others -- each a challenge, each a pleasure!

AI and indexing The Society of Indexers promotes quality indexes and improved standards and techniques of all forms of indexing. As part of our commitment to improving indexes,

Couldn’t indexing be done by a computer, or AI? No, because the usual problems with AI accuracy apply. It’s more efficient for a human to index a book for another human to use. We don't recommend AI or automated tools that can't meet indexing standards #IndexDay

Indexers really do read every word of each book, analyse the concepts presented and think how the reader will search for them. We must be highly accurate and also flexible to the needs of different books and clients. We have excellent vocabularies and are expert readers #IndexDay buff.ly/glTobKP

Ask the Indexers: what made you become an indexer? In our first Ask the Indexers post of 2026, we ask the indexers: what initially drew you to indexing, and how did you know it was the right fit? Valeria Padalin

So who are the indexers? We come from a wide variety of backgrounds and bring our professional experience and subject area knowledge to our indexing work. You can read about some of our members’ indexer origin stories in our blog post #IndexDay

Good indexes represent the book’s content in a balanced, accessible structure. And – of course – they are accurate. Explore our blog posts on index quality to learn more #IndexDay buff.ly/7bC7zgf

What is an index, and why is it important? An index is a map; it makes the information in books accessible to readers. It gives a sense of the coverage of the book, and whether it contains the information you need. And you can go back after reading to find what you want #IndexDay buff.ly/LMIHOqs
