Do abstracts vary by discipline (science, humanities, service, art, or performance)?
Abstracts do vary from discipline to discipline, and sometimes within disciplines. Abstracts in the hard sciences and social sciences often put more emphasis on methods than do abstracts in the humanities; humanities abstracts often spend much more time explaining their objective than science abstracts do. However, even within single disciplines, abstracts often differ. Check with a professor to find out about the expectations for an abstract in your discipline, and make sure to ask for examples of abstracts from your field.
