2nd topic

Primary, Secondary and Tertiary Sources 

       Ultimately we are done with our first topic and started with 2nd topic which is all about primary, secondary and tertiary sources of information. During the class we have learned about the primary sources of information. After having this class as far as I came to know about the primary source that "A primary source is an original object or document" and it is also called as the first hand information. A researcher can get the original or actual information by the primary sources because a primary sources generally write by the witnessed or experienced person. There are so many database which are considered as a primary source of information such as diaries, journals, speeches, audio or video recording and so on. Autobiography is also included as a primary sources because it is written by a person about his/her own life. After teaching this lesson our lecturer asked us several question which was related with this topic.

       After giving the lecture based on primary sources she started with the secondary sources of information. At first our miss gave us the brief definition of secondary sources and to be continuing she introduced us with the different example of secondary sources. From her meaningful interpretation I got the priceless suggestion about the secondary sources. During this class as far as I came to know about the secondary sources that "A secondary sources is written something about the primary sources". It is actually a second hand information. The great example of secondary sources are history books, textbooks, encyclopedias and so on. 

        In this session there was another sub topic which was about the tertiary sources of information. To be continue her lecture she gave us the proper definition of tertiary sources that "It is distillation and collection of primary and secondary sources." To make understand us clearly she gave us several examples and asked us the question. From my point of view tertiary sources is actually the collection of information from primary and secondary sources, it is also includes most types of references. The examples of tertiary sources are bibliographies of bibliography, directories of directory and guides to the literature.
