The comprehensive search for data that has been already published is called a literature search. In the scientific literature, the amount of published studies is gigantic, reason why finding the most relevant studies within a certain project can become a time-consuming and tedious task with so many databases available.
A literature search service will compile all data from primary (original studies), secondary (systematic reviews and meta-analyses), and tertiary literature (compilations, such as reference books) and provide an analysis of the data according to the main research question.
The systematic and effective search for previously published data is the foundation of all scientific, academic and pharmaceutical projects. Identifying previous studies and analyzing their results is usually the first step in any research project.
A literature review is usually based on a central, well formulated research question. Background data and recent developments are usually gathered and analyzed through the review.
The main reasons for performing a systematic literature search include:
Several different databases are available, with Medline (Pubmed) being among the most used in biomedical sciences due to the inclusion of 12 million indexed articles. The strategy behind a literature search relies on the use of keywords that are relevant to your research topic.
Reviewing the literature for a certain project requires several considerations, such as:
For many projects, a mere search is not enough, as the results for each keyword and each combination of keywords need to be tracked and recorded for different databases.
After identification of relevant articles, information needs to be retrieved from each abstract and, if necessary, the whole text needs to be accessed at this stage. Irrelevant articles are excluded from the search and the full-text articles are accessed, read and analyzed.
The studies are typically saved in a reference management software for easy retrieving and insertion in manuscripts at a later stage.
Data from each article included needs to be analyzed in relation to the research question and after compilation analysis of all studies included, conclusions must be drawn.
This entire process can be exhausting in the hands of busy professionals, reason many choose to pay someone to write the literature review for them.
Getting the job done by an expert chosen by you can cost as little as 30 USD per hour when using a-freelance platform.
Systematic reviews and meta-analysis are even more comprehensive than scoping reviews, requiring extensive resources. Hiring a freelancer can save time and money and a pre-agreed fixed rate can be the best solution in this case.
If you want to spend as little time as possible searching for a competent professional in literature review services, we recommend that you provide a detailed description of the work to be done:
Project description or scope of work: include the specific field, scope of work and all the details, so the freelancer can easily understand your needs and expectations.
Many professionals underestimate the amount of time that usually goes into a literature search. In order to optimize your time and improve workflow, you can pay for literature review and get quicker results from highly qualified professionals around the world.
