Classification of Source MaterialsHow can we locate the materials relevant to our topics better and faster? Basically, all these source materials may be classified into four majors of sources.A: Background sources:Basic information which can usually be found in dictionaries and encyclopedia complied by major scholars or founders of the field.Three very good and commonly recommenced encyclopedias areencyclopedias ABC, namely, Encyclopedia Americana, EncyclopediaBritannica, and Collier’s Encyclopedia. There are also referenceworks more specialized, such as The Encyclopedia of Language andLinguistics for linguistics and TEFL studies. Moreover, you mayalso find Encyclopedia on the web.B: Primary sourcesThose providing direct evidence, such as works of scholars of the field, biographies or autobiographies, memoirs, speeches, lectures, diaries, collection of letters, interviews, case studies, approaches, etc. Primary sources come in various shapes and sizes, and often you have to do a little bit of research about the source to make sureyou have correctly identified it. When a first search yields too fewresults, try searching by broader topic; when a search yields toomany results, refine your search by narrowing down your search.C: Secondary sourcesThose providing indirect evidence, such as research articles or papers, book reviews, assays, journal articles by experts in a given field, studies on authors or writers and their works, etc. Secondary sources will inform most of your writing in college. You will often be asked to research your topic using primary sources, but secondary sources will tell you which primary sources you should use and will help you interpret those primary sources.

There are two parts of a sourcethat you need to analyze: the text itself and the argument withinthe text.D: Web sourcesThe sources or information from websites. Web serves as an excellent resource for your materials. However, you need to selectand evaluate Web sources with special care for very often Websources lack quality control. You may start with search engines,such as Google, Yahoo, Ask, Excite, etc. It’s a good idea to trymore than one search engine, since each locates sources in its ownway. When using websites for information, be sure to take care forthe authorship and sponsorship. If they are both unclear, becritical when you use information. The currency of websiteinformation should also be taken into account. Don’t use too outinformation dated for your purpose.IV. Major strategies of Selecting Materials for literature reviewA.
