De Ware Tijd: de Ware Tijd (English: The True Time) is one of four daily newspapers in Paramaribo, Suriname.  s of 2002 , it was the largest-circulation paper in the country, ahead of its rival, "De West", and was described as taking a "staunchly independent stance" politically.

Winterreise: Winterreise ("Winter Journey") is a song cycle for voice and piano by Franz Schubert (D.  911, published as Op.  89 in 1828), a setting of 24 poems by Wilhelm Müller.  It is the second of Schubert's two great song cycles on Müller's poems, the earlier being "Die schöne Müllerin" (D. 795, Op. 25, 1823).  Both were originally written for tenor voice but are frequently transposed to suit other vocal ranges – the precedent being established by Schubert himself.  These two works have posed interpretative demands on listeners and performers due to their scale and structural coherence.  Although Ludwig van Beethoven's cycle "An die ferne Geliebte" ("To the Distant Beloved") had been published earlier, in 1816, Schubert's two cycles hold the foremost place in the history of the genre.

St. Irvyne: St. Irvyne; or, The Rosicrucian: A Romance is a Gothic horror novel written by Percy Bysshe Shelley in 1810 and published by John Joseph Stockdale in December of that year, dated 1811, in London anonymously as "by a Gentleman of the University of Oxford" while the author was an undergraduate.  The main character is Wolfstein, a solitary wanderer, who encounters Ginotti, an alchemist of the Rosicrucian or Rose Cross Order who seeks to impart the secret of immortality.  The book was reprinted in 1822 by Stockdale and in 1840 in "The Romancist and the Novelist's Library: The Best Works of the Best Authors, Vol.  III", edited by William Hazlitt.  The novella was a follow-up to Shelley's first prose work, "Zastrozzi", published earlier in 1810.  "St. Irvyne" was republished in 1986 by Oxford University Press as part of the World's Classics series along with "Zastrozzi" and in 2002 by Broadview Press.
