Profits at Harry Potter publisher Bloomsbury rose 8% to £13 million last year, driven by a 133% surge in sales of JK Rowling's bestselling children's series.
Revenue grew 11% to £123.7 million as a special illustrated edition of Harry Potter And The Philosopher's Stone gave the firm a major boost.
Bloomsbury's children's division saw sales increase by 57% to £41.8 million as a result, compared with £26.6 million last year.
Chief executive Nigel Newton said: "Bloomsbury has had a very good year with strong revenue and book sales growth, including a significant increase in digital sales."
Digital revenues grew by 24% year on year to £5.3 million, which the company said is more than treble the industry growth rate.
However, turnover at its adult publishing division dipped from £36 million to £32.7 million as the firm announced the "Bloomsbury 2020 strategy", which aims to increase revenues from digital academic material.
Mr Newton added: "We have set out the Bloomsbury 2020 strategy. This focuses on growing revenues from academic and professional digital resources for academic libraries worldwide, whose budget is estimated to be 5 billion US dollars (£3.4 billion)."
The boy wizard's magic will be worked again this year, with Bloomsbury signalling the release of an illustrated edition of Harry Potter And The Chamber Of Secrets.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
