I came across this today. It is my book. https://mocalra.cf/blogs/downloader-di- ... 58313.html This appears to be a Norwegian company who has converted it to an e-book and is giving it away, supposedly free for joining fees, of either £7.25 per month or £87 per year. The printed version sold out long ago, but I am still selling it as an E-book in PDF for Acrobat Reader via a reputable download site. Can I do anything about this. without risking high legal costs? - I am in the UK -
Sounds as if they're infringing your copyright (although I'm an engineer, not a lawyer).

Perhaps Citizens Advice is worth a visit beforehand.
They have apparently converted it to Italian as well (E-Book). Apparently, they want people to sign up with their site for £7.25 a month or £87 a year, and then they can download free E-books of which mine is one of many. Another site has it as well, and has converted it to French. Problem is, it would probably cost a fortune opening legal proceedsings against sites in other countries. If there was a "no win, no fee" copyright law firm, it would be worth taking it further, but I guess I will just have to grin and bear it it! As it has my ISBN number on it, it is beyond doubt that it is my book!
They have used your ISBN number but there are ways you can issue take-down notices:
