Literature review in research is a key step in doing successful, objective work. It helps to formulate a research question and to schedule the analysis. The published data available are huge;

therefore, it is an art to choose the correct articles relevant to our study. It can be time- consuming, be tiring and trigger disinterest or even to occasional abandonment of quest, if not done in a step-wise

manner.

In Brief

Introduction

A literature search is a well-organised and systematic survey from the already published data to become aware of a breadth of good pleasant references on a particular topic.

Formulating a well-focussed question is an important step for facilitating accurate scientific research.

Patient-oriented questions can involve the impact of remedy or disease or examine gain versus drawback for a set of patients.

Primary sources are the credible publication of new evidence, observations and statements from an expert (case studies, clinical trials, etc.)and a peer-reviewed journal which are generally published.Even primary literature includes draft studies, congress articles and preprints.

Secondary Sources

Primary Sources

Types of Literature

Secondary sources are publications of systematic review or meta-analysis, in which information extracted from primary source literature is inferred and analyzed.

Tertiary Sources

Tertiary literature consists of collections that gather knowledge (e.g. reference books) from primary or secondary research.

Methods of Literature Search

Searching the local as well as the national library over books, papers, etc. has been a common practice, and still, physical literature discovery is an essential component of any organized search process.

The conduct of a literature review includes web-based search engines, i.e. Google, Google Scholar, etc.

Databases for original published articles in journals and evidence-based databases for comprehensive knowledge are available as systematic reviews.

PubMed has been the most extensive available tool since 1996; however, a growing number of sources also offer free access to biomedical literature.

It should be assumed that synonyms / alternate words evoke additional information, i.e. barbiturates instead of thiopentone.

Medical Subject Heading (MeSH) is the structured hierarchical vocabulary of the National Library of Medicine that is used in PubMed to index papers, with more specific terms grouped under more general terms.

It is a reliable way to access quotes using different terminology for similar concepts since it indexes content-based posts.

Translating Keywords to Study Query

It will only provide pages with the words typed in the paragraph, in that exact order and with no words in between.

Phrase Search

AND, OR and NOT are the three Boolean operators named after the mathematicianGeorge Boole.

The combination of two words with' AND' will retrieve articles which reference both words.

Using' OR' will expand the search and fetch more items that address either subject.

While using the phrase' NOT' to combine terms, papers containing the first but not the second word will be fetched.

Boolean Operators

Example - article styles, text availability, language, age, sex and journal categories, filters may also be used to refine the search (Britannica, 1957).

Filters

Until investing time in subsequent data download, integration, and computational and visualization activities, perform a preliminary evaluation of the recovered data.

A quick review of the metadata (text and/or images) can often allow you to verify that the data complies with the initial requirements and constraints set out.

Many data repositories, such as the Arctic Data Center (https:/arcticdata.io) of the National Science Foundation, allow the data seeker to produce and download a metadata quality report which evaluates how well the metadata adheres to group best practices for discovery and reusability.

Assessment of Data Relevance

Literature search not only provides an opportunity to know more about a given topic but also provides insight into how previous researchers researched the topic.

It helps in understanding the concepts, find problems and consider opportunities.

Systematic and well-organized research can help with the development of novel research.
