Just type the word or phrase you’re looking 62 and click, there goes your answer. So why 63 wasting time turning the pages of encyclopedias if in just a snap of a finger you have what you needed People underestimate the power of encyclopedias. Well, technically, all of them are 64 sources which means, they are like the walls that can fully support your data. They are first hand accounts done by professionals and 65 . On the other hand, Internet information I’m not saying all of them, are 66 secondary, or third hand sources 67 basically means that they have been edited or 68 .They maybe data collected from several sources and were put together.

Unlike the one in the Internet, some people also tend to "copy-paste" their works 79 ever reading them. So they don’t absorb 80 must be absorbed. As they say, "No Pain, No Gain", so working hard with your research will surely be a 81 and a strong one.
