When I need to know new things, Internet search engines are the tools that I use to answer my questions right away. Today, there are so many search website such as Wikipedia, WorldCat as the library database and Google. The only remaining thing that I have to concern is about the credibility and reliability of this new information. That’s exactly how we have evaluating standards nowadays. For the Wikipedia, it gives me quick views of the information because all the data follow the same pattern; the definitions of the term of information always go on the top. That way, you can directly get the idea without reading the rest of the source. However, Wikipedia doesn’t have any credibility for academic writing assignment and this is the huge difference between Wikipedia and the library database. For the WorldCat, there are lots reliabilities and it is pretty to get citation from this source. Besides, I have to read the entire article to get the idea of the information, plus, some articles doesn’t seems to be accurate for what I look for even though their key words are matched. Additionally, the difference between WorldCat and Leonardo Electronic Almanac is the image that have been attached to each article on Leonardo website. With this advantage, researchers easily recognize how close their key words with the found related articles without reading them; it is a part of assisting method for the convenience of the researchers. In my opinion, Leonardo website has more reliabilities and credibility than Wikipedia; however, some articles will be hard to cite for academic writing assignments.
