As we are now a couple of weeks into 2017, authors who may have started their manuscript last year should update the copyright notice at the start of your book to reflect 2017 rather than last year.
You may have seen the manuscript templates that we offer to authors (with all the margins set properly) for 5x8 and 6x9 sizes - and have been updated to reflect "2017".
The templates are available in Microsoft Word format (both .doc and .docx) and also RTF format - so whatever type of word processing package you use (whether on a PC or Mac), use the latest templates and be sure your copyright message is the most up to date.
Happy writing!
