What is Citation Analysis?
The process whereby the impact or "quality" of an article is assessed by counting the number of times other authors mention it in their work.
Citation analysis invovles counting the number of times an article is cited by other works to measure the impact of a publicaton or author. The caviat however, there is no single citation analysis tools that collects all publications and their cited references. For a thorough analysis of the impact of an author or a publication, one needs to look in multiple databases to find all possible cited references. A number of resources are available at UIC that identify cited works including: Web of Science, Scopus, Google Scholar, and other databases with limited citation data.
To find out how much impact a particular article or author has had, by showing which other authors cited the work within their own papers. The H-Index is one specific method utilizing citation analysis to determine an individuals impact.
Web of Science provides citation counts for articles indexed within it. It indexes over 10,000 journals in the arts, humanities, sciences, and social sciences.
Scopus provide citation counts for articles indexed within it (limited to article written in 1996 and after). It indexes over 15,000 journals from over 4,000 international publishers across the disciplines.
Google Scholar provides citation counts for articles found within Google Scholar. Depending on the discipline and cited article, it may find more cited references than Web of Science or Scopus because overall, Google Scholar is indexing more journals and more publication types than other databases. Google Scholar is not specific about what is included in its tool but information is available on how Google obtains its content. Limiting searches to only publications by a specific author name is complicated in Google Scholar. Using Google Scholar Citations and creating your own profile will make it easy for you to create a list of publications included in Google Scholar. Using your Google Scholar Citations account, you can see the citation counts for your publications and have GS calculate your h-index. (You can also search Google Scholar by author name and the title of an article to retrieve citation information for a specific article.)

The h-index is an index to quantify an individual’s scientific research output (J.E. Hirsch)
The h-index is an index that attempts to measure both the scientific productivity and the apparent scientific impact of a scientist. The index is based on the set of the researcher's most cited papers and the number of citations that they have received in other people's publications (Wikipedia) A scientist has index h if h of [his/her] Np papers have at least h citations each, and the other (Np − h) papers have at most h citations each.
