Using a KEYWORD search in Worldcat, enter as much information as you have - for example, composer's name, title, opus number, thematic catalog number (e.g., the Köchel number for works by Mozart or the RV number for Vivaldi), key, instrumentation, and genre. Use the menus on the left side of the results list to limit your search to the FORMAT (music or CD, etc.) you want.
- Often, just the composer's name and the opus number, if known, will suffice. For example, to find Brahms' first violin sonata, (opus 78), type in KEYWORD search: brahms 78 and limit to "music."
- A less specific search may yield additional results if the piece is included in a larger collection. For example, expand your search for the opus 78 sonata by typing the KEYWORD search brahms violin sonatas (look at the entry for "Three sonatas for violin and piano").
- Truncate genre terms with an asterisk (*) so that Worldcat will search both singular and plural forms. Examples: sonata*, concerto*, symphon*, string quartet*.
