Academic writing is not really a genre in and of itself. Rather, it is a style of writing which encompasses many genres. Any type of writing that is circulated in academic circles or used for academic purposes can be included in academic writing. A simple example of academic writing would be a student essay or research paper. Another example of academic writing, especially at a collegiate or professional level, would be a critique. Literary criticism is a common for of academic writing; this is where the author reads, analyses, and might give a personal opinion on a particular work of literature. Although, critiques also appear in other areas as well. A scientific review would also be considered academic writing. Basically, anything that is written for an academic or scholastic purpose is considered academic writing. See the eNotes link below for a more comprehensive list.
