There are different types of plagiarism and all are serious
violations of academic honesty. We have defined the most common
types below and have provided links to examples. Direct
plagiarism is the word-for-word transcription of a section of
someone else’s work, without attribution and without quotation
marks. The deliberate plagiarism of someone else's work is
unethical, academically dishonest, and grounds for disciplinary
actions, including expulsion. [See example.] Self-plagiarism
occurs when a student submits his or her own previous work, or
mixes parts of previous works, without permission from all
professors involved. For example, it would be unacceptable to
incorporate part of a term paper you wrote in high school into a
paper assigned in a college course. Self-plagiarism also applies
to submitting the same piece of work for assignments in
different classes without previous permission from both
professors. Mosaic Plagiarism occurs when a student borrows
phrases from a source without using quotation mar
