New Hart’s Rules is on my list of recommended books, and it is recommended by the Society for Editors and Proofreaders (of which I am a member). The publisher describes New Hart’s as follows:
For over a hundred years, Hart’s Rules has been the authority on style, helping writers and editors prepare copy for publication. The latest edition of this guide has been updated for the twenty-first century using the resources of Oxford Dictionaries and with the advice of publishing experts. Twenty-one chapters give information on all aspects of writing and of preparing copy for publication, whether in print or electronically.

I often use New Hart’s as a source for blog posts and for information that I give to clients. It’s compact but thorough and detailed. It’s easy to find the information you need and helpful examples are given. It may not directly address all possible scenarios (something The Chicago Manual of Style seems to have attempted) but the style guidance is easily applied in most circumstances.
Of course, it is important to point out that New Hart’s is a style guide and ‘correct’ style is often subjective. For example, Oxford style prefers -ize spellings for verbs but other styles may not agree. However, New Hart’s generally acknowledges areas where some style guides may give different advice.
When I started out as a proofreader, I found the chapters on how to style work titles, quotations and direct speech, and numbers and dates particularly helpful (as evidenced by the multitude of sticky notes all over my well-thumbed first copy). I think self-publishers would find it helpful as a guide to standards that would be acceptable in traditional British publishing and how to attain those standards in their own work.
The most recent edition of New Hart’s was (at the time of writing) released in 2014. The 2005 edition is, as far as I am aware, still perfectly serviceable, but the 2014 edition is updated and contains an extra chapter (on the differences between US and British English). It’s available in most bookshops and through online retailers, including Wordery and Amazon. You can also access it online for free if your library card gives you access to Oxford University Press resources – you can read more about that here.
If you have a copy or use the online version, please let me know what you think of it!
