The “literature” is the written conversation between scientists about what they’ve found out (by reading or experimenting).Searching the literature is all about learning who the cool people are and where they hang out.
Research process is iterative – as you learn more, you constantly refine your strategies and even your research question.For the best research questions, the answer doesn’t exist yet! You’re looking for clues that will let you piece together the puzzle yourself.

How not to reinvent the wheelor Literature Searching for ENCH400 2012
Our mission is… Literature review on a topic Proposal Lots of research Mass balances – calculations Look for different processing routes Oral presentation and report Experiments Report
We already know... We get information from: Internet – Google, Wikipedia People – Lecturers, mentors, other students Library resources: Textbooks MultiSearch ScienceDirect Google Scholar Journals (browsing by subject)
We need to know... How to find papers Structure and layout of the literature review What to include and what not to include How do you know if it’s a good article or not? Methods to include the information without directly copying
The Research ProcessDefine your topic What information do you need? Who would have written about it? Where? Find information Judge it – is it reliable? relevant? – does it point in new directions? – is it enough? or do you still need more? Analyse and synthesise Cite all sources!
Choosing keywords What criteria do I use in choosing keywords to search for? • Choose the main words from the initial question If not enough results: • Use fewer words (or broader synonyms) • Use the root of words – eg magnetic*, produc* If too many results: • Use more words (or more specific synonyms) • Exclude subjects – NOT methanol (Google Scholar uses -methanol instead) • Search for a phrase with quotes eg “lysine production”
Evaluating resourcesIs it… and... relevant? Who is it written for? basic/advanced? What kind of research is it? up-to-date? How far along is the research? What questions haven’t they answered yet? accurate?
Filtering results How do I refine/filter the search results to get useful and reliable resources? • Read the title • Read the abstract • Check the keywords – can use these in new searches • Check the article’s reference list for older articles • Check who else has cited the article for newer research • Use the “Refine” column to narrow by subject, author, year, document type (eg “review” articles for an overview of the state of research)
