Reading, Excerpting or Copying?
There is a very simple answer: always read first. Of course, not word for word, but first overview. Obtain as much literature as possible and check if the lyrics are of any use to you. If you want to find the really important texts, you have to read a lot and fly over them. So sort it out quickly, but make a note of all the titles, combined with a brief assessment. (I recommend working with a paper box or a computer database.)
Thoroughly reading and, if necessary, copying important passages from them is worthwhile for what you recognize to be particularly important. Yes, you have read correctly: “write off” (tapping is of course synonymous). This has the particular advantage that the text is thereby fragmentarily stored in the mind – you have the corresponding quotations later while writing the work already mentally available and can use them in the appropriate place. What you copy on the other hand, without having read it, you forget immediately. To an even greater extent, this applies to Internet downloads. Therefore the rule: Copy or download always with simultaneous, meaningful entry in database, paper box or work plan!
Presentation of the research literature
Research literature should not only be read, but also mentioned. After all, your work also serves as proof that you know and can classify the research literature. In most of the theses – no matter if it’s a diploma thesis, a master’s thesis or a bachelor thesis – you have to give a kind of overview of the state of science (often also called state of research or research report) on your topic. This includes presenting the most important (not all!) Works of current research literature and their theses thematically arranged. Again, it is advisable to consult with an expert: The golden mean between fearful long–windedness and – even worse – ignorance of important research results alone is difficult.
Scientific rules of the game
There is not much to pay attention to. Two important principles are nevertheless mentioned:
Any good scientific work should be based on theses. The meaningfulness of these theses is scientifically justified at the beginning. At the end of the thesis, you present as a result of the investigation whether or to what extent the theses could be confirmed.
Your own opinion may be expressed throughout the text. However, it must always be clearly separated from the train of thought of the actual investigation. In particular, the choice of the subject matter of the examination should not depend on expressed personal preferences. Avoid the impression that you are writing about your favorite private topic and formulate it as objectively as possible and distanced.
