Copyright and Plagiarism

Copyright / Notice and take down:

We are sorry we cannot check each text for copyright infringement due to the high degree of automation of our publication process. Therefore we offer a notice and take down process. If you notice a copyright infringement, please tell our support at info@grin.com. We will immediately take down the queried text and check its legitimacy in corporation with the author.

Plagiarism:

Many professors and college teachers publish their texts with GRIN, besides we cooperate with colleges like HdM StuttgartUniversity of Mainz and University of Bremen. Renowned media publishers report regularly and positively about our services. Nevertheless we are often confronted with the subject “plagiarism”.

We don’t support cheating and plagiarism. We offer an archive full of valuable scientific information.
Professors and teachers may use our websites as control media of plagiarism. If there is a suspicion of plagiarism from one of our eBooks, just contact us. We help you to find out if your student has plagiarised.

A closer cooperation between teachers and students through mentoring already in the early stages of writing can help to avoid cheating. In this way the level of knowledge and progress of the student can be tested. Furthermore, teachers should ask their students to use the latest literature and define the subject in detail to prevent plagiarism.

GRIN promotes science

By publishing texts in our archive, science itself is brought forward. It cannot be the goal of college education to let students analyse the same subjects over and over again. Basic matters can be checked with written examinations.

Important notice to all users of our service: copying works from others is a copyright infringement!
