Citations can be tracked in a variety of databases. Some databases, tools, and other platforms have varied coverage of the Humanities. Many of these allow searching by author, publication, or journal. To determine if a database suits your individual needs, click on the link and attempt to search.
Metrics, also known as research metrics or bibliometrics, is a measurement of scholarly research using quantitative methods such as citation counts, downloads, mentions, and more. Metrics are also used to demonstrate the impact of research publications at the journal, article, and author levels, which help faculty and researchers show the reach of their scholarship for tenure and promotion, job opportunities, and grant funding, among other things.
Altmetrics is used to refer to "alternative metrics" and are generally article-level metrics. Altmetrics attempts to fill a gap in more traditional metrics by using a more comprehensive range of sources, such as social media, news outlets, blog posts, and citation managers, in addition to citation and download counts to determine the impact (or "attention") of scholarship.
None of these are tools designed specifically for tracking citations of books or published in books. The best you can do is search through the full text of books to identify citations to your work.
Here are some large collections of academic books that are full-text searchable.
