The so-called Studienbuch O (Notebook “O”) is an octavo volume (10 x 15.5 cm.), 164 sheets, with a gray-green cover. Written on the cover by an unknown hand: "Excerpta mit verschiedenen Bemerkungen". Text is in brown and black ink. Sheets have been numbered in pencil by a librarian in the upper-right corners, and so pages here are indicated as ‘1r’, ‘1v’, ‘2r’, etc. Some sheets are missing, others are added.
Most entries appear to be written while Herder was in Riga [Irmscher/Adler 1979, 241]; a book mentioned on 163v was published in 1765.
Previous transcriptions: None of the pages listed here have been previously transcribed in Irmscher  or the Academy edition.
A few entries of particular interest:
• A detailed taxonomy of human knowledge (certainly not of his own invention, but perhaps collected from various sources?) (2r-5r, 8r-14v). At 11v-13v, which concerns natural theology, Herder includes comments on arguments regarding God's existence.
• Plato on recollection (29v-32r, 34r-34v, 37r, 38r).
• On the origin of the uselessness of metaphysics (c. 1763-64?) (70r-71v).
• On the usefulness of philosophy for the state and for the well-being of the people (c.1764?) (73v, 74r).
• How time can change everything (c. 1766?)(67r-68v).
• Philosophical dreams, based on new discoveries (84r).
• A reading or lecture schedule (164r).
[While this notebook entry is of interest, the mention of the book by Anthony Ellys, below, indicates that it stems from Herder’s years in Riga, rather than when he was a student at Königsberg.]

 [Brumoi] Pierre Brumoy (1688-1742) was a French classicist: Théâtre des Grecs (1730) is referenced in Herder’s Kritische Wälder [FHA 2: 99].
 [Blackwell] Thomas Blackwell (1701-1757) (Aberdeen), Enquiry into the Life and Writings of Homer (1735) developed a theory of epic poetry. He taught at King’s College, Aberdeen, where one of his students was James Macpherson (1736-1796), who later wrote the six-volume Fingal, an Ancient Epic Poem (London, 1762), putatively composed by Ossian, the blind and ancient Gaelic poet and son of Fingal. This and related works by Macpherson enjoyed international acclaim, and Ossian, a “Homer of the North,” played a significant role in the Sturm und Drang movement in Germany, where Herder introduced Goethe to Macpherson’s writings (Ossian makes an appearance in Werther) and Herder would later publish Auszug aus einem Briefwechsel über Ossian und die Lieder alter Völker [Extract from a Correspondence about Ossian and the Songs of Ancient Peoples](1773).
 [Reinhard] Adolph Friedrich von Reinhard, 1726-83) studied at Halle and was trained in law but also wrote on a wide variety of philosophical topics, even winning the 1755 Prussian Academy prize essay contest on optimism. He defended free will in his Réflexions sur la liberté (1762), which is possibly the reference here.
 [Premontvals] ‘Prémontval’ was the assumed name of André Pierre le Guay [1716-1764]. His Du Hasard (1755) was mentioned in Herder’s Journal meiner Reise im Jahr 1769, in a passage criticizing the intellectuals surrounding Friedrich the Great (FHA 9.2: 71).
