Scholarly journal articles may seem to be the most popular information source.
So why are different types of information sources such as books, trade magazines, market research reports important to a researcher?
Watch this video to learn about the different types of information sources that you can use for your academic research.
What is a scholarly journal or a peer-reviewed journal?
Scholarly journals (or academic journals or peer-reviewed journals) give new, ground-breaking and original research. They show research methods, processes and applications.
Scholarly journals are ranked by some indicators, and scholarly journal articles go through a peer review process.
Before a journal article is accepted for publication, it has to go through a peer review process. This is when submitted articles are reviewed by your peers before publication. The purpose is to determine whether your research is of quality or good enough to be published.
There are different types of peer review process:
NUS Libraries occasionally organise talks by publishers about their reviewing process. Watch out for NUS Libraries' newsletter.
Books give the big picture, an overview or background of a topic. If you are uncertain of a particular topic, it is best to start with books. Books give definitions and introduces a topic or technology. The screenshot of a below shows a definition of membranes.
Handbooks are compilation of essential information such as facts, figures, graphs, equations, illustrations and charts, etc. The example below shows an e-book titled the Membranes Handbook. It includes definition of membrane and the membrane process, etc.
Other examples of handbooks are:

New ideas or preliminary research or work-in-progress. Researchers eager to seek resources from interested parties would present their ideas at conferences to foster collaborations with their peers.
Full-text of conference papers are sometimes available in major databases such as Scopus and Engineering Village.
Papers presented at conferences are published as proceedings.
Some examples are:
The purpose of a patent is to protect a technical concept, process or product for a number of years.
If people want to use your invention and your patent is protected, they have to pay you royalties or wait for your patent to end or buy over your patent.
In supporting research, patents:
Patents filing is a long process. ILO (Industry Liaison Office) helps in patents filing in NUS.
NUS Libraries conduct tutorial on patents searching. Watch out for NUS Libraries' newsletter.
To locate patents in NUS Libraries, refer to Patents Subject Guide.
Theses and Dissertations allow you to find out what research work has been done by other Masters and PhD students.
In NUS Libraries, there are 2 databases to search for theses:
To find out how to search for theses, refer to How do I find theses?
How to browse for NUS Engineering theses in ScholarBank?

3. Click on ETD to access Electronic Theses & Dissertations
4. Click on Department
5. Click on the Engineering department, for example, Civil & Environment Engineering. A list of theses appears, then sort by Issue Date in Descending Order if you want the latest theses to be listed first.
Annual reviews give an expert’s overview of recent developments and highlights significant work. Trends and developments of a particular technology or invention are generally published as a review article.
Compare these 2 journal articles. The review article gives an overall understanding of forward osmosis.
Some examples are:
Use annual reviews along with books to start building your knowledge on a particular topic.
Trade magazines give news analysis, product reviews, market analysis, market information, and industry happenings that will guide the application of your invention or research. It shows application of technologies in industries.
Trade magazines tell you what is happening in the business world. They guide you in thinking of your invention not just as a great idea but what companies or consumers may use or buy.
Some examples are:
Market research reports or industry research reports analyze information about the market, the product or service or consumers. As an engineer you would want to invent something that companies or consumers would buy. To secure funding, investors and stakeholders may want to know which market is best for your invention.
These screenshots below show data of the desalination market in Asia Pacific region taken from Frost & Sullivan.
Some examples of market research databases are:

Standards are sets of specifications on how certain materials or products should be manufactured, defined, measured or tested.
Some national or international standards bodies which issue standards are:
Some similar standards are adopted by some standards bodies. For example:
NUS Libraries does not subscribe to ISO or EN but has BSOL (British Standards Online). Therefore, you can still find ISO 9001 through BSOL.
To locate standards in NUS Libraries, refer to Standards Subject Guide.
