In relation to the above, I really don쳌ft see any difference in posting actual excerpts from already published, copyrighted works or links to them of any kind, whether they be bits of texts from research documents, libraries etc.

Also, I쳌fm at a loss as to the allusion to plagiarism.
The term means to copy another쳌fs work then pass it off as one쳌fs own for gain or otherwise.
