Summarize the following:
For an APA reference entry, list the poet's last name first, followed by a comma. Then type the first initial of the poet's first name. Even if the poem is included in an edited anthology, use the poet's name rather than the editor's name. Example: Pope, A. After the poet's name, include the year the poem was published. Use the year the poem you read was published, not the year the poem was originally published. Place a period after the closing parentheses mark.  Example: Pope, A. (1963). If there is no date of publication (such as with poems published online), use the abbreviation "n.d." For example: Herrick, R. (n.d.). If the poem appears in a book of collected poems by the same poet, your full reference entry cites the work as a whole, rather than the individual poem. Write the title in sentence-case, capitalizing only the first word and any proper nouns in the title. Include the first initial and last name of any editor in parentheses. Place a period at the end. Example: Pope, A. (1963). The poems of Alexander Pope (J. Butt, Ed.). If a poem appears in an anthology of poems by different poets, type the title of the poem, using sentence-case. Place a period at the end of the poem's title. Then type the word "In," followed by the first initial and last name of the editor of the anthology. Place a comma, then provide the title of the anthology in italics, followed by the pages where the poem appears in parentheses. Place a period after the closing parentheses mark. Example: Cleveland, J. (1972). To the state of love, or the senses festival. In H. Gardner (Ed.), The metaphysical poets (pp. 218-220). For poems online, the title of the poem itself follows immediately after the date of publication. Type the title in sentence-case, capitalizing only the first word and any proper nouns. Place a period at the end of the title. Example: Herrick, R. (n.d.) To daffodils. For print sources, include the location and name of the publisher, separated by a colon. Place a period at the end. For poems published online, type "Retrieved from" followed by the direct URL for the poem. Do not place a poem at the end of the URL.  Collection example: Pope, A. (1963). The poems of Alexander Pope (J. Butt, Ed.). London: Methuen.  Anthology example: Cleveland, J. (1972) To the state of love, or the senses festival. In H. Gardner (Ed.), The metaphysical poets (pp. 218-220). Harmonsworth: Penguin. Online example: Herrick, R. (n.d.) To daffodils. Retrieved from http://quotations.about.com/cs/poemlyrics/a/To_Daffodils.htm APA style uses author-date parenthetical citations in-text. In most cases, the citation follows immediately after any title or quotation from the poem. There is no need to include the poet's name in the citation if it is included in your text.  Example: In Ode for Music, on St. Cecilia's Day (Pope, 1963), the poet writes a holiday poem that could be set to music. If there was no publication date, use the abbreviation "n.d." as you did in the reference list entry. For example: To daffodils (Herrick, n.d.) shows the poet's treatment of life's fleetingness.

Summary:
List the poet's name first in your full reference entry. Provide the year of publication in parentheses. Italicize the title of a single-author collection. Type the title of the poem if it appears in an anthology. Type the title of the poem in italics if you found it online. Include publication information for the source. Use the poet's name and date of publication for parenthetical citations in-text.
