1. There are two major texts for locating analyses of works. They include titles of articles and books that discuss and analyze composer's works.
You can also try the UT Analysis Index, but note that call numbers in this database refer to the UT Library holdings, but search our catalog to see if we own the titles in question.
2. If the work you are studying is not included in Diamond or Hoek, search the library catalog for books that may include analysis of your piece.
Some examples of subject headings in the library catalog that might help you find analysis:
3. You can also search in journal databases like RILM and Music Index to find individual articles and dissertations about the piece.
4. Finally, you can also try looking in the composer's bio-biobibliography (or guide to research) if there is one to see if it lists any analyses.
When Grove doesn't list the person you are looking for, or doesn't include very much information, you can try using the biographical dictionaries listed below.
In addition, there are also book-length biographical tools called bio-bibliographies, which is a bibliography devoted to one composer or concept (like string quartets). They list books, journal articles, and other information about a composer. Sometimes these books are called "guides to research" or "research and information guides". They are typically located in the ML134s in the Reference collection.
Sometimes it can be difficult to find biographical information about composers who are still living. Some good sources are publisher websites and interviews (either online or in newspapers and periodicals).
