And where is the plagiarism, if there is a link to the source? I don't see that OP is trying to claim the authorship of this material...
Plagiarism is the "wrongful appropriation" and "stealing and publication" of another author's "language, thoughts, ideas, or expressions" and the representation of them as one's own original work.
