I'm happy to oblige. Here are more books to add to your (ideally short) bookshelf on short writing:

Headlines are more important than ever in building traffic, and captions never allow enough room. This guide walks you through structure, traps, pitfalls and the actual mechanics of writing headlines and captions, with exercises to try.
- Copywriting: Headline Wizardry: Learn How to Write Spellbinding Headlines, by Jack Chapman, takes a different tack, dissecting headlines by their purposes, tone and intent. You won't look at a headline the same way again.
- Letting Go of the Words, Second Edition: Writing Web Content that Works includes clear-writing advice as well as content strategy for websites, SEO and social media.
- Get to the Point! Painless Advice for Writing Memos, Letters and Emails Your Colleagues and Clients Will Understand, Second Edition deals with our most common forms of day-to-day writing, not noble but necessary.
