Will Web Search Engines Replace Bibliographic Databases in the Systematic Identification of Research?

Abstract

Will web search engines replace bibliographic databases in the systematic identification of research? AbstractThe availability of web search engines provides opportunities in addition to those provided by bibliographic databases for identifying academic literature, but their usefulness for retrieving research is uncertain. A rigorous literature search was undertaken to investigate whether web search engines might replace bibliographic databases, using empirical research in health and social care as a case study. Eight databases and five web search engines were searched between 20 July and 6 August 2015. Sixteen unique studies that compared at least one database with at least one web search engine were examined, as well as drawing lessons from the authors' own search process. Web search engines were limited in that the searcher cannot be certain that the principles of Boolean logic will apply and they were more limited than bibliographic databases in their functions such as exporting abstracts. Recommendations are made for improving the rigour and quality of reporting studies of academic literature searching.

A study of the determinants of postgraduate students’ satisfaction of using online research databases

“…Academic librarians frequently guide library users in their quest for relevant information materials. As the quantity of available information continues to grow, the task of retrieving relevant information becomes more and more challenging [19]. Academic libraries all over the world are experiencing a paradigm shift in acquiring, storing and retrieving information, because of the application of information communication technologies (ICTs).…”

A Human Machine Hybrid Approach for Systematic Reviews and Maps in International Development and Social Impact Sectors

“…The metadata sets of the publications registered in the databases are not standardized. It is common to have multiple versions of the same publication [15,16]. In addition, authors of publications may inadvertently "obscure" their articles by using loosely related popular terms in the titles and keywords, decreasing the specificity of articles to increase the likelihood of the article being indexed in and prioritized by the query engines, as titles play an essential role in making publications accessible to search engines and attractive to users [17].…”

Qualitative research synthesis: An appreciative and critical introduction

“…For example, there are very few available PubMed MeSH search terms to filter searches on this extensive database. Bates et al (2017) found in a systematic review that web search engines were not as effective as were bibliographic databases in aiding the location of academic publications. While they did not specify whether they sought a particular research methodology (i.e.…”
