Search tips

Wikisource recommends that users of this site amend their default search preferences. We recommend that you use the setting

  • Redirect mode with subphrase matching (advanced).

This setting allows searching subpages and redirects for your search term.

Wikisource reproduces many fiction and non-fiction works using content in subpages, placed under the title page of the work. This can include poetry, essays, biographical and scientific articles, etc. For this reason, your search term may not display or may not be prioritised if you use the default search setting.
