The 2018 revision broadens the scope of the manual, by including style requirements for all four APSA membership-wide academic journals. The 2018 revision also embraces a decade’s worth of changes to the academic publishing world. A few of these changes include: manuscript tracking systems, online-only publications, open-access journals, social media, active-citation techniques, data archives, government research funding requirements, and more.
