Aims & Objectives
• Edit and refine searches;
• Search across multiple resources;
• Use alternative search options, including citation searching;
• Save searches and keep up to date;
• Find the full text of items not available at LSHTM;
• Keep accurate records of searches;
• Keep within copyright, data protection, research data management and intellectual property restrictions.
This class builds on the information covered in the first class and links advanced techniques into the 6 steps to an effective literature search. It covers how to:
![Page 3: Systematic literature searching Information skills for PhD students: 2 Jane Falconer Improving health worldwide.](https://reader034.fdocuments.in/reader034/viewer/2022052702/5697bf9f1a28abf838c94e96/html5/thumbnails/3.jpg)
Six steps to an effective literature search:
1.• Scoping your search topic
2.• Choosing the resources to search
3.• Choosing your search terms
4.• Compiling your search strategy and running your search
5.• Finding the full text
6• Managing your information
![Page 4: Systematic literature searching Information skills for PhD students: 2 Jane Falconer Improving health worldwide.](https://reader034.fdocuments.in/reader034/viewer/2022052702/5697bf9f1a28abf838c94e96/html5/thumbnails/4.jpg)
Are you looking in the right place?
Are you using all of the relevant search terms?
Have you used the Boolean Operators
correctly?
Can you simplify your question to include less
concepts?
I can’t find any information
Are you sure there is any information out there to find?
![Page 5: Systematic literature searching Information skills for PhD students: 2 Jane Falconer Improving health worldwide.](https://reader034.fdocuments.in/reader034/viewer/2022052702/5697bf9f1a28abf838c94e96/html5/thumbnails/5.jpg)
Are your search terms finding irrelevant results?
Have you added limits?
Can you split your search into smaller ‘chunks’?
Can you narrow your search concepts?
I have found too much information
Some topics have LOTS of information and there is little you can do about it
![Page 6: Systematic literature searching Information skills for PhD students: 2 Jane Falconer Improving health worldwide.](https://reader034.fdocuments.in/reader034/viewer/2022052702/5697bf9f1a28abf838c94e96/html5/thumbnails/6.jpg)
Have you searched all relevant resources?
Have you included all relevant search terms?
Is your search syntax correct?Can you ask experts in the field for details of additional
information?
I think I might have missed
some information
Remember to leave enough time to complete all of your searching

Search filters
Compiled by InterTASC
• http://www.york.ac.uk/inst/crd/intertasc/
Tested search strategies to find specific study methodologies• Often tested on multiple databases
Used in conjunction with subject search
• Run subject search and search filter then use AND to combine together

Do NOT...
• Search for items authored by specific people
• Search for items published in specific publications
• Search for items published by a known institution or research group
This will introduce bias into your search results and could impact the reliability of your subsequent research.
This is particularly important if you are conducting a systematic review.

By taking steps to manage your data, you can:
“Data produced during the research activity should be managed appropriately, ensuring that it is stored, organised and documented in
a manner that allows it to be understood and used for the intended purpose.”
LSHTM Research Degrees Handbook
Ensure your data will be suitable
for analysis
Anticipate problems and
reduce likelihood they will occur
Save time and effort
Communicate objectives to
your supervisor
Recognise support needs
Address research
obligations & requirements
