Finding Articles and Books Using Database for your Discipline

In brief
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.

I. 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. One should conduct the
literature search to identify appropriate
methodology, the layout of the study;
populace sampled and sampling methods,
methods of measuring principles and
strategies of analysis. It also helps in
determining irrelevant variables affecting
the outcome and figuring out faults or
lacunae that would be avoided.
Formulating a well-focussed question is an
important step for facilitating accurate
scientific research. There may be trendy
questions or patient-orientated questions
that get up from medical issues. Patient-
oriented questions can involve the impact
of remedy or disease or examine gain
versus drawback for a set of patients
(Grewal et al., 2016).
II. TYPES OF LITERATURE
Primary Sources
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
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.
III. METHOD OF LITERATURE
SEARCH
Various methods of literature
analysis are used alone or in combination.
For the past few decades, 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. Through
technology progressing, the Internet is
now the gateway to the labyrinth of vast
medical literature. The conduct of a
literature review includes web-based
search engines, i.e. Google, Google
Scholar, etc., or the use of various online
research sources to classify materials that

reflect the research topic or those that are
homologous to it (Martínez-García et al.,
2019).
Databases for original published
articles in journals and evidence-based
databases for comprehensive knowledge
are available as systematic reviews and
abstracts among the various databases used
for literature search. Most of these are not
freely available to individual users.
PubMed has been the most extensive
available tool since 1996; however, a
growing number of sources also offer free
access to biomedical literature. PubMed
contains more than 26 million citations
from Pubmed, life science journals and
online books.
The choice of databases depends
on the topic of interest and potential
coverage by the various databases.
Education Resources Information Center is
a free digital online educational research
and information library funded by the US
Institute of Education Sciences. Education
department, available via
http:/eric.ed.gov/. Only one site is allowed
to search all of the medical literature.
Many different repositories are required.
At least, it is crucial to scan for PubMed or
Medline, Embase and the Cochrane
Central Trials Database. A meta-analysis,
systematic reviews, randomized controlled
trials and seminal research need to
highlighted when searching such
databases.
IV. TRANSLATING KEYWORDS TO
STUDY QUERY
It will yield results based on any of
the stated words; hence, they are the
cornerstone of a successful quest. 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.
V. PHRASE SEARCH
It will only provide pages with the
words typed in the paragraph, in that exact
order and with no words in between.
VI. BOOLEAN OPERATORS
AND, OR and NOT are the three
Boolean operators named after the
mathematician George 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,
thereby narrowing the search.
VII. FILTERS
Of example, article styles, text
availability, language, age, sex and journal
categories, filters may also be used to
refine the search (Britannica, 1957).
VIII. ASSESSMENT OF DATA
RELEVANCE
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. Ideally, the metadata
will also provide ample details to
thoroughly determine the validity and
fitness for data use, including information
on how the data was collected and quality
assured, how the data was previously used,
and so on.

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
(Wilkinson et al., 2016).
IX. FUTURE SCOPES
Study issue is usually a subject of
interest to the researcher and some
familiarity. When reflecting on
information, yet to be discovered, it needs
to be channelled. Once the problem has
been narrowed down, the search for and
review of existing literature may further
streamline the approach to study.
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. In
short, systematic and well-organized
research can help with the development of
novel research.
