DATABASE SEARCH RESULTS : DATABASE COMPARISONS : DATABASES: MEDICAL: Finding Database Content, Comparisons, Evaluations and the Nature of Content Shared in Selected Medical Databases from Database Search Results

David P. Dillard






Finding Database Content, Comparisons, Evaluations
and the Nature of Content Shared
in Selected Medical Databases from Database Search Results



These links may help with this question.  I also believe that the value of
databases is not just determined by the content provided, but also by the
search features of the platform it is found on as finding content is as
important as the content being available in a database.  Search capabilities
are particularly important in the worlds of evidence based, systematic
reviews and the meta-analysis as the quality and thoroughness of search
results for projects involving these.  Expect many false drops in these
results, but there also seems to be a substantial collection of on topic
sources as well.  The first group of links compares Embase with
Pubmed and the second group adds Web of Science and Scopus to the mix.
There will also be comparisons of PubMed to Medline and Pubmed Central
which may be helpful to some users of this post. Methods sections of
publications that discuss specific topics may also provide clues to
comparative database usefulness in searches for the content shared in
those research studies.
