When it comes to the popularity of books, we're all aware of the best-seller lists that tell us how many copies have been sold.
But in this digital age many of us consume novels digitally on an e-reader or by listening on audiobook.
Amazon is the market leader when it comes to such matters - with its hugely-popular Kindle and Audible platforms.
So we thought it would be interesting to look at which books were most read in 2023, taking account of these new ways to enjoy storytelling.
These are the top 10 - and they're pretty different from the traditional best-sellers of the year, which you can see here.
9. Lessons in Chemistry by Bonnie Garmus
Assisted by a major Apple TV series starring Brie Larson, Lessons in Chemistry was the most-read non-wizarding work of fiction in 2023. "Chemist Elizabeth Zott is not your average woman. In fact, she would be the first to point out that there is no such thing. But it's the early 1960s and her all-male team at Hastings Research Institute take a very unscientific view of equality. Forced to leave her job at the institute, she soon finds herself the reluctant star of America's most beloved cooking show, Supper at Six." | Contributed
10. The Thursday Murder Club by Richard Osman
The fourth in the series of television host Richard Osman's crime books set in a retirement village may have come out this year and become an instant best-seller - but it's the original that was the most read this year. "In a peaceful retirement village, four unlikely friends meet up once a week to investigate unsolved killings. But when a brutal killing takes place on their very doorstep, the Thursday Murder Club find themselves in the middle of their first live case. Elizabeth, Joyce, Ibrahim and Ron, might be pushing 80, but they still have a few tricks up their sleeves. Can our unorthodox but brilliant gang catch the killer before it's too late?" | Contributed
