The conclusion that all three tools are needed is <em>defensible<\/em>, though it could be argued that each search tool is used for quite different purposes.<\/p>\n<p>The challenge with comparative studies like this? Study design is difficult. The problem (or challenge) is the issue of coverage in each source, which is <em>markedly different.<\/em> And, in the case of Google scholar, we don&#8217;t know what is covered.<\/p>\n<p>It seems obvious to librarians that <em><u>Google scholar is <u><strong>not<\/strong><\/u> a reliable citation tool<\/u><\/em> (though the <u><em>cited by feature<\/em><\/u> is generally viewed as useful). &#8220;Cited by&#8221; in GS is only meant to be an <em>indicator<\/em> of citedness, and to lead to other scholarship. Results should be contextualized by comparing the <em>same searches<\/em> in WoS.<\/p>\n<p><em><strong>Conclusion?
