Message from our Honorary President
Caroline Sanderson
It’s my huge pleasure and privilege to serve as Honorary President of the Society of Indexers (SI), succeeding the admirable Sam Leith.
I’ve worked as a freelance writer and books journalist for the best part of 30 years, with non-fiction my speciality. So throughout my career I’ve benefitted from an incalculable number of indexes. In fact I first consulted indexes many years before that as a nerdy child with a large collection of reference books.
I’m delighted to have this opportunity to advocate for the beauty and utility of a good index and – in an era when we are grappling with the potential and the pitfalls of artificial intelligence – the human acuity that is indispensable to making one.
So, whether you are a publisher, an author or a reader, please browse this website, where you’ll find out exactly how integral the work of a professional indexer is to the books that you publish, write, consult and enjoy.
