When all else fails, the book quotes itself. One passage appears three times.
Periodicals and Short Fiction
The New-York Weekly Magazine, Or, Miscellaneous Repository: Volume II, 1797. Reprinted as a single bound volume containing 52 8-page issues (July 1796-June 1797). “NY Weekly”
Only two volumes of this periodical, and a few issues of the third, were published; only volume II was available to me. At least 30 separate pieces are quoted in Alida, so it is likely that some unidentified sources are in volumes I or III.
Most essays were printed with minimal attribution, or none at all; some can also be found in other sources. “The Nettle and the Rose” also appears in The Blossoms of Morality (1796) and in New-York Magazine, N.S. II (1797). “On Education” is taken from the writings of Vicesimus Knox; “Detraction” is by Nathaniel Cotton.
“Amelia, or the Faithless Briton”. Here quoted from The New-York Magazine, or, Literary Repository: Vol. VI (1795); the story also appears in The Lady’s Weekly Miscellany (1810).
“The Merchant’s Daughter”. Here quoted from The American Monthly Magazine, Vol. 3, 1834.
“The Story of an Unfortunate Young Lady”. Here quoted from The Lady’s Miscellany, or, Weekly visitor... Vols. 14–15 (1811)
Poetry
Most poems are quoted only once, and will be identified as they appear. The author of Alida was obviously fond of poetry, especially obscure poems found in periodicals or privately published books.
