The measurement of book impact is in the beginning stages. For this reason it seems to be necessary to focus on book reviews, "cited by" numbers and availability in academic libraries.
Several databases contain scholarly book reviews:
- JSTOR
- PhilPapers
- Project Muse
- Scopus
Number cited by available.
- Google Scholar
After a search for the title of a book, the search result list shows how often the book was cited by other authors.
- WorldCat
WorldCat is a shared catalog of millions of library holdings. It is possible to see which libraries own a copy of a certain book.
