Article evaluation
After reading the article about Copyright on Wikipedia, I think everything in the article is relevant to the article topic. It gave a brave detail of the copyright background and give out different similar topic that have close relation with the copyright, such as Copywritting, legal rights, exclusive rights, etc. I believed that the article is neutral because it does not have anything that show a particular position toward any side. The contents of the article were well organized into many sub-titles and cover all the basic. I also checked some citation links that provide at the bottom of the article, for those I tried all work well and it does support the article itself. Moreover, most of the citations were cited from books which show it is a reliable references. Although the information is up to date, it can cover more countries that have to do with copyright. It only have US and the UK mentioned in the article, it can evaluate more how copyright affect or the mean about copyright to places around world. Although some citation are from reliable sources, the article were cited Class-C WikiProject assessment meaning the article still have lack of support from more reliable sources. The Wikipedia covered all the basic of copyright, however, it does not go into too much detail like we did in class. It needs us to search on our own for more relevant or sub-title in order to understand more about the concept of copyright.
