Legal / Terms
For eBooks and printed books, the same copyright is effective. Both can be acquired only for private or other single person use. Copies, reproduction or distribution is only permitted with explicit permission of the author or the publisher. The user is responsible for observing these law prescriptions and is liable for abuse.
If you cite a text literally, the author has to be mentioned - omitting this is a copyright infringement. Whole ebooks must not be put on other websites for download.
It is prohibited to publish GRIN documents elsewhere (e.g. websites, databases, etc.). Please use the embed-code of a document to show the flash version of GRIN documents on a blog or website.
Please read our terms of service.
Plagiarism
Even if many professors and teachers publish their works on GRIN, we are sometimes 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 texts, 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 avoiding cheating. So the knowledge of the student concerning the subject can be checked at his point of time. 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 itsself 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.
Notice to all users of our archive: Copying works from others is a copyright infringement!
