Here's a snapshot of what I think is published for the first time in January 2023 (and is usually a UK date but occasionally will be a US or Australian date). January and future months can be found on the Future Releases page. If I've missed anything or got the date wrong, do please leave a comment.
Please note that, unless specifically mentioned, when a book has differing print and ebook release date, I use the print release date. Translators' names are included where known.
