"Eastern poem on the death of Pushkin" is an elegy of Azerbaijani author Mirza Fatali Akhundov, composed in 1837 in Persian.
 This poem was his first published work.
 In 1837 Akhundov prepared a Russian prose translation of his poem, and his friend Bestuzhev a versified one.
 First time the poem was published in the journal "Moskovskiy Telegraph" (Akhundov's translation).
 The poem was also published in the journal "Moskovskiĭ Nablyudatel", with an editorial note welcoming the poem as a tribute not merely to Pushkin but to Russian culture as a whole.
 Translation of Bestuzhev was published in 1874 in journal "Russkaya Starina".
 Original version of the poem was found and published only in 1936 (translator Pavel Antokolsky).
"Space Age Love Song" is a 1982 single released by the British band, A Flock of Seagulls.
 It was their fourth single.
 Lead guitarist Paul Reynolds remarked on their 1984 video album "Through the Looking Glass" that he thought of the song's title.
 He said that the band wrote and recorded it, but couldn't come up with the title.
 He suggested "Space Age Love Song" because he thought it sounded like a space age love song.
 His idea stuck as the song's permanent title.
The Haunting Of Alaizabel Cray (2001) is a Gothic steampunk horror/alternate history novel by Chris Wooding about a Victorian London overrun by the wych-kin, demonic creatures that have rendered the city uninhabitable south of the river, and which stalk the streets after dark.
 When Thaniel Fox, a young wych-hunter, finds a mad girl wandering the streets in the middle of the night, he is moved by pity to take her home; and in doing so, he becomes embroiled in a plot that reaches into the highest levels of government, and into the darkest depths of the wych-kin's world.
Roy Croft is a poet frequently given credit for writing a poem titled "Love" and beginning "I love you not only for what you are, but for what I am when I am with you."
.
 The poem, which is commonly used in wedding speeches and readings is quoted frequently.
 It was included in a 1936 anthology entitled "Best Loved Poems of American People", edited by a Hazel Felleman, and published by Doubleday (ISBN  ) and appears without further attribution in "The Family Book of Best Loved Poems", edited by David L. George and published in 1952 by Doubleday & Company, Inc., then of Garden City, New York.
 German translations of the poem circulate with the title "Ich liebe Dich" ("I Love You") but are (wrongly) credited to the Austrian poet Erich Fried.
 The translation(s) led to the speculation that the poem was just a translation of Erich Fried's work and Roy Croft was a pseudonym used by a translator who wanted to keep all royalties from publication (rather than sharing them with Fried's estate) or who simply did not want to go through the trouble of obtaining a license from a foreign entity.
 Taking into account that the poem was already published in 1936 (where Erich Fried was only 15) it seems very unlikely that Erich Fried could be the author.
"An Old Fashioned Love Song" is a 1971 song written by Paul Williams and performed by the American pop-rock band Three Dog Night.
 Chuck Negron performed the lead vocal on this track.
 Taken as the lead single from their 1971 album, "Harmony", the song peaked at number four on the "Billboard" Hot 100 chart in December 1971, becoming the band's seventh top-ten hit.
 It was Three Dog Night's first record to top the U.S. easy listening chart.
 It reached number two in Canada.
 Its lyrics suggest the straightforward and melodic nature of the tune: "Just an old fashioned love song / Comin' down in three part harmony / Just an old fashioned love song / One I'm sure they wrote for you and me".
"Secret Love Song" is a song recorded by British girl group Little Mix for their third studio album, "Get Weird" (2015).
 It features guest vocals from American singer Jason Derulo, who co-wrote the song with Jez Ashurst, Emma Rohan, and Tich.
 It was produced by Jayson DeZuzio.
 The group's cover of Derulo's 2015 single "Want to Want Me" inspired him to collaborate with them.
 "Secret Love Song" is a slow ballad comprising pounding bass and melancholic strings.
 The lyrics discuss unrequited and forbidden love, while Derulo's verse details his personal experience of having an affair.

The Bell Jar is the only novel written by the American writer and poet Sylvia Plath.
 Originally published under the pseudonym "Victoria Lucas" in 1963, the novel is semi-autobiographical, with the names of places and people changed.
 The book is often regarded as a "roman à clef" since the protagonist's descent into mental illness parallels Plath's own experiences with what may have been clinical depression.
 Plath died by suicide a month after its first UK publication.
 The novel was published under Plath's name for the first time in 1967 and was not published in the United States until 1971, in accordance with the wishes of both Plath's husband, Ted Hughes, and her mother.
 The novel has been translated into nearly a dozen languages.
 The novel, though dark, is often read in high school English classes.
