Suppose person A has a research project where they need to find a few articles on a particular topic, and write a review of these papers.
Being busy with other coursework, and feeling overwhelmed by the task of searching papers, person A decides to ask person B for help to find a list of articles on the topic. Person B is not a student in the course, but is willing to help person A.
Person A then reads the articles B found and writes their paper on their own.
Has there been plagiarism or other ethical violation committed?
EDIT: An additional concern is whether person A needs to credit person B's work. The goal of the paper would be to develop understanding of the field that the course is about, not specifically train for literature search. The submission will be graded.
