A literature review is:
1) A list of books and journal articles,
2) on a specific topic,
3) grouped by theme,
4) and evaluated with regard to your research. This evaluation would identify connections, contradictions and gaps in the literature you have found.
The purpose of a literature review, therefore, is:
1) To get a feel for the agreed academic opinion on the subject (the connections).
2) To discover the disagreements on the subject (the contradictions).
3) To find opportunities, (the gaps), for developing and expressing your own opinions.
The classic pattern of academic arguments is
THESIS, ANTITHESIS, SYNTHESIS
(Yeah, Yeah, I know …Hegel thought of it first…)
An Idea (Thesis) is proposed, an opposing Idea (Antithesis) is proposed, and a revised Idea incorporating (Synthesis) the opposing Idea is arrived at. This revised idea sometimes sparks another opposing idea, another synthesis, and so on…
If you can show this pattern at work in your literature review, and, above all, if you can suggest a new synthesis of two opposing views, or demolish one of the opposing views, then you are almost certainly on the right track.
Steps in compiling a literature review are:
1) Select a specific topic (the more focussed, the better, or you’ll go on for ever).
2) Collect the most relevant (usually “peer reviewed”) books and articles.
3) Read/skim them, using the abstract (a short summary attached to the article).
4) Group the articles into the sub-themes of your topic.
5) Identify within each sub-theme those points on which the articles agree, those points on which they disagree, and those points which they don’t cover at all.
1) Choosing your topic
Seek
advice from a lecturer or tutor on this, if a topic is not already
assigned. It is very common for students to bite off more than they can
chew, simply because they have not realised the full breadth and
complexity of an apparently simple topic. It is better to cover a tiny
topic perfectly, than a huge topic superficially.
Look
for a topic on which there is polarised opinion. It often helps to pick
one in which a question is being asked, for example: Is a particular
taxation policy beneficial or disadvantageous to a developing country?
When
authors disagree, this provides an opportunity for you to enter the
debate and argue for one side or another in your essay. Taking a
hatchet to someone’s opinions (a) gives you something to write about,
(b) is fun, (c) is the foundation of much modern scholarly writing.
2) Collect the most relevant (usually “peer reviewed”) articles and books
The
two tools for finding these books and articles are (a) the library
catalogue and (b) the library databases of electronic journal articles.
Before
you search them, spend a minute thinking about the best terms to use.
Make a list of alternative words that describe your subject, and also
think about general terms and more specific terms. This is important
because the journal databases are good for finding very specific terms
in articles, but the library catalogue tends to use more general terms.
To access the library catalogue go to www.lib.uct.ac.za and click on “Catalogue”.
If
you find a good book reference, scroll down to the bottom of the
reference and you will find the subject terms the library cataloguers
have assigned to it. Click on that term to call up more books just like
the one you have found.
A
quick way to check the relevance of any books you find is to glance at
the table of contents, the introduction and any descriptive blurbs on
the back cover. The index at the back of the book not only helps you
dive to very narrow topics in the book, but also gives you an
indication of how much attention (i.e. how many pages) the book spends
on that specific topic.
If
you are satisfied with the book, look at the bibliography in the back –
this can help identify other relevant sources. Following a chain of
references in a bibliography like this, whether in a book or a journal
article, is one of the most basic techniques of scholarship – find
something that is relevant and look at the sources it used.
The library’s journal databases
are particularly helpful for literature reviews. Journal articles are
short and cover very specific topics, so they are more digestible than
books and more likely to deal exactly with your topic. They are also
quicker to publish than books and so are more likely to be up to date.
To find journal articles by subject go to the library home page at www.lib.uct.ac.za and select “Databases.”
Many
of these databases allow you to restrict your search to “Peer Reviewed”
journals only – these are the most scholarly journals, for which each
article has to be vetted by other academics before it is accepted.
Many
of our databases are Full Text – so you can usually get the whole
article on your desktop for downloading, e-mailing or printing – you
don’t have to find it in print on the shelves.
While you can search the Research Portal, or individual journal databases, as simply as you search Google, you can also type in very precise searches by using And, Or, Not operators, Wildcards and Logical Brackets.
An example of such a search would be:
Information Technology AND Brain Drain AND (Employ* OR Jobs OR Labo?r) NOT United States
3) Read/Skim the articles, using their abstracts
Most of the articles will have an abstract.
This is a short paragraph at the head of the article that lists the
main facts and arguments in each article. By reading these you will
quickly get the gist of what each article is about and where it fits
into the pattern you are building up in your literature survey.
How
many books and articles should you have? It’s wise to check this with
your lecturer or tutor. In general, though, your aim is not to cover
every single book or article, but every major opinion or theme on the
topic. Many of the books or articles will add very little that is new.
Therefore a short list of really scholarly, relevant, comprehensive articles is often more effective than a list of hundreds of superficial or tangential articles.
What you are ideally looking for are the “seminal” articles (seed articles) on which most of the other authors are basing their work.
4) Group the Articles into the themes and sub-themes of your topic
Obviously,
it helps to have a structure in mind already, but the articles you find
will often help to suggest a structure or cause you to redesign your
existing one.
Herewith a hard-learned tip:
There are tides and seasons in academic publishing – a topic is often hot for a few months, then dies, then is revived to be attacked from a different angle, then dies, then is revived again to be discussed from a third angle… remember, Thesis, Antithesis and Synthesis?
This has two implications for studying the results on a database search:
For example, in a list of journal articles on Information Technology and Employment you might find that:
See? Story!
Many
database lists of academic articles tell this sort of story when they
are looked at in date order. Either they reflect swings in world events
or they are reflecting swings in academic debate and opinion. Seeing such a story in the literature is a great help in structuring any literature review.
In
particular, look out for the major triggers of such changes: When did
the first swing to a new track happen, and what event or article
provoked it?
When
you find an article that has provoked a major swing, or started a whole
new debate, then you are looking at the “Seminal” (Seed) article that I
mentioned earlier. This sort of article is often the best sort of
article to identify in a literature review – many of the other articles
will just build on, comment on, or attack its basic arguments.
Using a Citation Database
If
you find a seed article, or any other really good article, we have a
magic database, called the ISI Citation Database, which can find all
the other articles which have cited that article, either because they
support it or because they disagree with it.
The
ISI Citation Database is on our database list under ISI WEB OF SCIENCE.
There are three versions of it, covering the Sciences, Social Sciences,
and Arts and Humanities. You can search all three at once.
Go
to “Cited Ref Search” and type in the author’s last name, the journal
in which his article appeared and the year it appeared in the
appropriate boxes. This will bring up the authors and articles that have followed or disagreed with that author.
Unfortunately
this database is not full text, but you can often get the full text of
the articles off one or other of our alternative databases.
5) Identify
within each sub-theme those points on which the articles agree, those
points on which they disagree, and those points which they don’t cover
at all.
The abstracts can help with this, of course. The main trick is coming up with, or spotting, the sub themes and that is simply a matter of brain work. But
if it is done well, and you have taken the trouble to find good
sources, then you will find, quite magically, that you have constructed
the skeleton and a good bit of the flesh and blood of your essay or
research project.
In fact, a good literature review can result in an essay that virtually writes itself.
