 Second week was bit interesting. From the start lecturer taught us about primary and secondary sources.


Primary sources: are original materials. Information for which the writer has no personal knowledge is not primary, although it may be used by historians in the absence of a primary source. In the study of history as an academic discipline, a primary source (also called original source orevidence) is an artifact, a document, a recording, or other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions are used in library science,library science, and other areas of scholarship. In journalism, a primary source can be a person with direct knowledge of a situation, or a document created by such a person.












Secondary sources: is a document or recording that relates or discusses information originally presented elsewhere. A secondary source contrasts with a primary source which is an original source of the information being discussed; a primary source can be a person with direct knowledge of a situation, or a document created by such a person
Secondary sources involve generalization, analysis, synthesis, interpretation, or evaluation of the original information. Primary and secondary are relative terms, and some sources may be classified as primary or secondary, depending on how it is used. An even higher level, the tertiary source such as an encyclopedia or dictionary, resembles a secondary source in that it contains analysis, but attempts to provide a broad introductory overview of a topic.
Lecturer also explained about the example of both primary and secondary Sources. She told us about Diaries, journals, autobiographies that it comes under primary sources.
Secondary Sources usually is in the form of published works, journal articles, books, radio and tv documentaries come under Secondary sources.














Tertiary Sources:
Bibliographies of bibliography
Directories of directories
Guides to the literature
Directories come under tertiary example.

Furthermore she taught us about Library, that part was really interesting because we never go to library but that day i actually came to know about the meaning of Library.
I have never come across the services which library provide us, that day I came to know that library is actually for
Book lending
Reading room
Printing
Photocopy
Information search
Current awareness service
E-journals
Multimedia collection
It became more interesting when we learnt about encyclopedia. ENCYCLOPEDIA is something really informative and useful. Information literacy is a really informative subject, moreover I learnt about types of Encyclopedia and Dictionary. As we all used to know about Dictionaries.
Our lecturer also told us some meaningful facts about Glossary, lexicon, thesaurus, vocabulary.
I just remember OPAC (online Public access catalog) was really tough as we can see from the name.

OPAC:



—OPAC is a computerized online catalog of all the materials held in a library and can be searched quickly and efficiently using a computer. At last she taught us about networks.
