Database-Specific Searching Tips

Bibliographic Searching:
Author and Title: When entering authors or titles, punctuation and spacing must match exactly that in the on-line bibliography.
Date: The works in the database currently range in date of publication from 1803 to 1981.
Theme: To limit one's search to a particular theme, simply enter the theme into the Theme Field. One may search more than one theme at a time; the vertical bar ( | ) serves as the OR operator (e.g., entering Law and Society|Economic Development searches both).
  • African-Americans
  • Black Hawk War
  • Campaign of 1858
  • DeKalb
  • Economic Development
  • Frontier Settlement
  • Law and Society
  • Lincoln
  • Native American Relations
  • Political Development
  • Presidential Campaigns
  • Religion and Culture
  • Women and Gender
Genre: To limit one's search to a particular genre, simply enter the genre into the Genre Field. One may search more than one genre at a time; the vertical bar ( | ) serves as the OR operator (e.g., entering memoir|autobiography searches both).
  • advice literature
  • article
  • autobiography
  • biography
  • diary
  • fiction
  • government document
  • history
  • interview
  • letter
  • memoir
  • narrative
  • note
  • pamphlet
  • poetry
  • political tract
  • proceedings
  • reminiscence
  • sermon
  • song
  • speech
  • travelogue
Orthographic Considerations:
No unusual orthography has been detected in this database. Expect elisions such as wing'd and 'neath. Both British and American spellings of words have been entered (e.g., honour and honor).
Wildcard characters or Boolean operators can help detect such inconsistencies. One could enter wing.d or hono.?r or honor|honour to achieve the desired results.

Data-Entry Idiosyncrasies:
Several data errors have been detected in some databases either from typesetting errors in the original source or from converting the documents. One should avoid making arguments from silence. In particular, look out for confusion from similarity of letters (e.g., vvest for west) and word-clustering.

Punctuation and Full-Text Searching:
Hyphens: Hypens act as word separators. Thus, one should treat hypenated expressions as separate words excluding the hyphen (e.g. if searching for ever-changing, type in ever changing.)
Apostrophes: One must include apostrophes when searching words with apostrophes in them (e.g., only by typing god's will one find "God's"). In this database apostrophes do not act as word separators. Therefore contractions and elisions must be entered without spaces before or after the apostrophe.
Ampersands: The ampersand (&) is not a searchable character. Avoid Phrase Searches where an ampersand may be used as a conjunction.

Formatting and Display:
Notes: There are notes throughout the database. In PhiloLogic notes never interfere when searching the text to which they refer. Note references are linked to notes and text from notes are linked to page references, but not from a first-level results screen.
Images: There are several images throughout the database. Inline images and links to non-inline images display once the user pulls up any level of context (e.g., page, paragraph, h3, h2, and h1), but not from a first-level results screen.
Sound: Buttons for the RealAudio sound files are located at the beginning of documents. Click on the title and the first section after "header." The RealPlayer is required to listen to sound files. Download Now
