Google Scholar tracks cited by of all kinds of resources (journal articles, books, book chapters, dissertations, etc.)
Word of caution....
It's difficult to track dates and publications that are included in Google Scholar. Also, it has been reported that Google Scholar has incorrectly identified reviewers as authors and journal titles as article titles. So, it shouldn't be the only metric you report.
iCite is a tool to access a dashboard of bibliometrics for papers associated with a portfolio. Users type in a PubMed query or upload the PubMed IDs of articles of interest, optionally grouping IDs for comparison. iCite then displays the number of articles, articles per year, citations per year, and Relative Citation Ratio.
