To choose the best formatting option for publication titles, it is important to balance 2 needs:
- showing clearly what phrase represents the formal title for a work
- maximising legibility and readability on both screen and on paper.
Formatting choices have been regularly evolving with writing technology. When text was hand-written, we tended to use capital letters (title case) to show that a phrase was the title of a published work. As book printing evolved, we added italic formatting to distinguish between the titles of published and unpublished works.
But business documents presented a problem, because typewriters did not offer italics. So in workplace and academic documents not published through a printing press, we turned to capitals and underlining to format publication titles.
The recent move toward minimal capitalisation shifted government style in Australia to sentence case for publication titles, where only the first word is capitalised. While formally published works kept their italics, it wasn't clear where the title ended for unpublished titles in roman text. Many used quote marks or reverted to title case.
Most recently, we have found that italics presents problems for reading onscreen because the sloped letters are harder to capture in pixels on a monitor. So we've been moving away from italic formatting in general.
Taking all of these factors into account, the ASG recommends returning to title case for both published and unpublished titles, but moving away from italics.
We recognise this represents a significant departure for many writers. But it is an adjustment worth making for the digital age.
