Elsevier Compendex and Google Scholar: A Quantitative Comparison of Two Resources for Engineering Research and an Update to Prior Comparisons     

Jeremy Cusker 《The Journal of Academic Librarianship》2013

Elsevier's Compendex product (and its ancestor, Engineering Index) has been a de rigeur indexing tool for searching the primary literature in engineering for many years. However, the price of Compendex continues to rise while at the same time, broader, lower-cost or even free alternatives to such expensive indexing tools have proliferated. This paper seeks to quantitatively and, to a lesser extent, qualitatively compare Compendex to Google Scholar.  相似文献
