Google Scholar - Coggle Diagram

- - - - Book Coverage
        
        It is a huge advantage, as books are barely present even as an indexing/abstracting record, let alone as a completely indexed, full-
        text item in most of the other multidisciplinary mega-databases.
      - Geographic and language coverage
        
        It is a typical limitation of even the subscription-based scholarly databases that they often almost exclusively cover only anglophone sources,predominantly published in the USA, UK, Australia and Canada.
  - - - It speaks volumes about the limitations of the software that when using the query term <the> (the most commonly occurring English word), Google Scholar yields a hit count of over 1.5 billion records, whether you are using it with or without the + sign or surround it by double quotation marks (as it is supposed to be a stop word without these signs, but apparently it is not).
        
        Oddly, restricting the search to the seven listed subject groups will increase the result to 105,000.
