Any arguments you present in a thesis must be grounded on your own analysis and on research that has been published before. It is vital to have clear and logical source annotation so that the reader will know what you base your claims on. Source references give the reader the opportunity to learn more about the topic. In theses, you can also use source references to prove that you are well-read and have expert knowledge about your field.
The main point about references is that they have to contain enough information, and that they are presented in the same way throughout one publication. An in-text reference should be indicated so that the reader clearly can see the difference between the quoted part and the author’s own analysis. The in-text reference should also direct the reader to the correct place in the list of reference with more detailed information about the source.
The list of references or bibliography should give detailed enough information about the source, so that the reader can go back to the source to check facts. The list of reference should contain exact bibliographic data, i.e. name of author and title of work, publishing data (name of publisher, and publishing location and date), and possibly name of series or journal. The text reference and the bibliographic data must correspond exactly, so that it is easy to find the source in the list of reference!
Learn to indicate references accurately, carefully and logically from the start of your studies.
Waiting for the bus, Raymond suddenly met his suspicious acquaintance, Arso Nist, who said he had heard that Raymond was preparing an assignment for the course Unbearable Lightness of Studying. Nist was interested in Raymond’s topic. Nist kindly pointed out quite a few references he had listed in his blog, and offered them for Raymond to use. Raymond found Nist’s blog and noticed that, in fact, many of the references had Arso Nist inappropriately listed as one of the authors. After checking the references in the database and concluding that Nist was blatantly spreading falsified references, Raymond sent him a stern message, emphasising the importance of keeping to good academic practice.
Different reference styles (APA, CBE, Chicago,Harvard, Vancouver etc) are used in different fields. In practice, you will always have to find out which style to use from your degree programme or thesis supervisor. You will be instructed by the course lecturer or Instructions for Students about which format to use in your study assignments and theses. Some examples below:
APA (American Psychological Association) reference style
In text: (Regehr, Glancy, & Pitts, 2013)
Reference list: Regehr, C., Glancy, D., & Pitts, A. (2013). Interventions to reduce stress in university students: A review and meta-analysis. Journal of Affective Disorders, 148(1), 1-11. doi:http://dx.doi.org/10.1016/j.jad.2012.11.026
Harvard reference style
In text: (Regehr, Glancy et al. 2013)
Reference: REGEHR, C., GLANCY, D. and PITTS, A., 2013. Interventions to reduce stress in university students: a review and meta-analysis. Journal of affective disorders, 148(1), pp. 1-11.
From the reference you can see:
authors: Regehr, C., Glancy, D., & Pitts, A.
title of the article: Interventions to reduce stress in university students: A review and meta-analysis
publication year: 2013
journal where the article is published: Journal of affective disorders
volume of the journal: 148
issue of the journal within that volume: 1
page numers: 1-11
digital object identifier (doi); persistent identifier used to uniquely identify the document: http://dx.doi.org/10.1016/j.jad.2012.11.026
Electronic information sources are cited basically with the same priciples as the printed sources. For web pages it is good the mention also the url or DOI of the page and the date when you accessed the information.
Reference management programs make it possible to gather academic references into a database. This allows you to create a list of references at the end of your document according to your own template, for example, or arrange references according to use, remove double references, and make information searches among the references. There are many different reference-management programs, such as Mendeley, Zotero and EndNote.
