Research is not just academic

Finding a phone number

Ordering a takeaway

Selecting a broadband provider

Joining a gym

Information-seeking

Think about a time recently when you were looking for information.

How did you identify that you needed information?

What did you do to find the information you required (if you were successful!)?

When did you stop looking?

Planning a searchWhat is your research question?

How else could you ask it?

Could it be broken down to smaller questions?

Does the question‟s verb inform your approach?

What level and quality of information is needed?

Do you need up-to-date or historical sources?

Information sources

Anywhere you find information can be called a source. But some sources are not as reliable as others.

Match the information sources to their strengths and weaknesses.

Think about how these strengths can be used for an assignment, and what you could do to compensate for the weaknesses.

Unreliable sources

Anonymous authors

Bias in information provided

Unsupported or out-of-date information

Heavy usage of non-academic style

Populist or sensational focus

This applies to magazines as well as certain websites…

Sorting results

No quick answer, but the following help:

„Sort by date‟ brings up-to-date information to the top of the search list

„Sort by relevancy‟ will order the results according to what the program thinks you want using complex „learning‟ algorithms.

„Sort by availability‟ removes inaccessible sources from the search list, reducing wasted time trying to access them.

Common retrieval problems

I‟ve got 5m results - information overload!

your search is too broad. Filter, sort or start again

I‟ve got no results!

Your search is too narrow. Re-calibrate your filters and try broader or alternate terms

I‟ve found something which looks good, but can‟t get to read it!

If it is an SNC library item, reserve it

If you found it using Google, check our subscriptions

Check if you could read it with walk-in access at the local universities

It may involve extra work, but a key source can make the difference between a good grade and a great one!
