To find books containing the works of an author, search the MERLIN library catalog by Author, family name first.
You can also expand your search to MOBIUS, which includes the East Asian Library at Washington University in St. Louis. Books from other MOBIUS libraries can be requested through the catalog and will be delivered within a few days. Your MU ID card is also a library card at MOBIUS libraries.
Note that names may be transcribed from non-Roman characters in a variety of ways.
Note also that collected works may not list the individual titles of plays or poems in the catalog record. You may need to physically check an index volume or table of contents to find the specific piece you are looking for.
You may also search in Google Books. Copyright restrictions may prevent you from seeing the entire book online, but this works as an online index to books you can then find in the library. The advanced search is more precise.
To find works published contemporaneously with historic events, use MERLIN and other library catalogs.
