Definition and examples:
1) an act or instance of using or closely imitating the language and thoughts of another author without authorization and the representation of that author's work as one's own, as by not crediting the original author: it is said that he plagiarized Thoreau's plagiarism of a line written by Montaigne.
2) a piece of writing or other work reflecting such unauthorized use or imitation: "These two manuscripts are clearly plagiarisms", the editor said, tossing them angrily on the floor.

We at Diesel Bob (UK) Ltd have spent many, many years learning all the intricate workings of diesel injection components and have uploaded some of the more basic information up to our website.
It is know that other diesel oriented firms (with no connection to us at all) have blatantly copied some of our text and some of our pictures to their own websites but lack the common decency to acknowledge that the text/pictures originated from Diesel Bob (UK) Ltd!
Please be aware that copying information is a desperate measure and if a firm lacks the intuition to upload there own thoughts then one would suspect the quality of the product they supply may well be 'lacking' too.
