Turabian (and its parent, the Chicago Manual of Style) documentation format has a consistent rationale:

• Each note (whether footnotes or endnotes) is a single sentence.
  • The only period is at the end of the citation.
  • Only commas and semi-colons, and colons occur within the citation.
  • Series and publishing information is included in a parenthesis at the end of the note, before the period.
• Book:
  • Author’s first name, last name, Title: subtitle (Place of publication: Publisher, date), page(s).
• Journal article:
  • Author’s first name, last name, “Article title,” Journal Title vol. no., issue no. (date [including month or season, if present]): page or page-page, url [if accessed online].
• Edited book:
  • Editor’s first name, last name, ed., Title: subtitle (Series; Place of publication: Publisher, date).
• Edited book [multiple editors]:
  • first name, last name; first name, last name; first name, last name, eds., Title: subtitle (Series; Place of publication: Publisher, date).
• Article in book:
  • Name, “Article title” in Book Title: subtitle, ed. Name(s), page-page (Series; Place of publication: Publisher, date).

Bibliography citations, on the other hand, are not a sentence. Periods occur after each basic unit:

• Book:
  • Author’s last name, first name. Title. Series. Place of publication: Publisher, date.
• Journal article:
  • Author’s last name, first name. “Title.” Journal title vol. no., issue no. (Date [including month or season, if present]): page-page. url [if accessed online].
• Edited book:
  • Editor’s last name, first name, ed., Title: subtitle. Series. Place of publication: Publisher, date.
• Edited book [multiple editors]:
  • Last name, First name; First name, Last name; First name, Last name, eds. Title: Subtitle. Series. Place of publication: Publisher, date.
• Article in book:
  • Last name, first name. “Article title.” In Book Title: Subtitle, ed. first name, last name(s), page-page. Series. Place of publication: Publisher, date.

Your syllabus specifies that you should use a standard format for your paper. These would include Turabian/Chicago Manual of Style, APA, and MLA.

Purdue University has a helpful website for all of the standard citation styles:
