Bibliometrics are one way to measure the impact of your research, which can be useful for your own interest, or when applying for jobs, grants, or tenure and promotion. Bibliometrics include citation counts, citation impact, h-index, and journal impact factor. However, these measures can exclude public scholarship (e.g. social media, blog posts, newspaper articles), conference proceedings, syllabus listings, and other ways work is used beyond academic publications - so be critical of how you assess the work of yourself and others. Some ways to start measuring research impact are below:
Citation chaining or citation mining is when you use an information source to find related sources. It is a great way to find more research on a topic which interests you, and to illustrate how research builds on previous work and changes over time. You can find related articles by looking at the works cited section of a work, or by using tools like Scopus and Google Scholar.
