Primary Source Searching - Names
One of the most powerful ways to find primary sources in the Library is to use the names of people. An essential part of your background reading should be to note down names of people involved in your topics.
Names can be searched in the catalogs [Oskicat and Melvyl] in specialized ways: as authors or as subjects. Even people you do not consider authors in the conventional sense may be listed as authors, if:
- their correspondence is available
- their manuscripts are available
- interviews with them are available
- their diaries are available
- published versions of these are available
When searching for primary sources, it's a good idea always to search those names as authors, as well as keywords. Works where the person is listed as an author will always be primary sources.
