Johannes Jacobus Smith (Antwerp 29 June 1867 – Oegstgeest 14 January 1947) (sometimes written as Joannes Jacobus Smith) was a Dutch botanist who, between years 1905 to 1924, crossed the islands of the Dutch East Indies (mainly Java), collecting specimens of plants and describing and cataloguing the flora of these islands.
 The standard botanical author abbreviation J.J.Sm.
 is applied to plants described by J.J. Smith.

Noah's Ark is a picture book written and illustrated by Peter Spier, first published by Doubleday in 1977.
 The text includes Spier's translation of "The Flood" by Jacobus Revius, a 17th-century poem telling the Bible story of Noah's Ark.
 According to "Kirkus Reviews", the poem comprises sixty three-syllable lines such as "Pair by pair" (in translation).
 "Without revising or even enlarging on the old story, Spier fills it in, delightfully."
Giacomo Mazzocchi, in Latin on his titlepages Jacobus Mazochius, (active 1505 — 1527) was a learned bookseller, printer, and noted antiquarian in papal Rome during the High Renaissance.
 A native of Bergamo, Mazzocchi is first heard of in 1505 as provider of finance for an edition of Vibius Sequester "De fluminibus" printed by J. Besicken of Rome.
 By 1509 Mazzocchi was himself in business as a printer.
 For humanists he might publish such scholarly works as the first printed repertory of Roman inscriptions, "Epigrammata Antiquae Urbis" (April 1521), a folio of some 3,000 inscriptions, mostly of epitaphs, in which his collaborator was the Florentine priest Francesco Albertini This work includes inscriptions ranging from Roman Republican times to the age of Justinian I and is illustrated with somewhat stylised woodcuts showing some of the buildings and monuments of Rome, such as the Pantheon, the Arch of Constantine and the Pyramid of Cestius.
Günther Zainer (or Zeyner or Zeiner) (died 1 October 1478) was the first printer in Augsburg, where he worked from 1468 until his death; he produced about 80 books including two German editions of the Bible and the first printed calendar.
 He came to Augsburg from Strassburg and printed in 1472–76 three large works of moral instruction.
 He also printed the first large illustrated book, Jacobus de Voragine's "Legenda aurea" in 2 volumes with 131 woodcuts, 1471–76.
 Johann Zainer, the first printer in Ulm, was probably his brother.
Tim Jacobus (born April 21, 1959) is an American artist best known for illustrating the covers for nearly 100 books in R. L. Stine's "Goosebumps" series.
 He has done over 300 book covers and paintings for various different series, novels, and video games.
 He currently resides in New Jersey, doing most of his art digitally.
 A complete list of his work is unknown, but below is a list of a few of the things he worked on.
Murderous Maths is a series of British educational books by author Kjartan Poskitt.
 Most of the books in the series are illustrated by illustrator and author Philip Reeve, with the exception of "The Secret Life of Codes", which is illustrated by Ian Baker, "The Essential Arithmetricks: How to plus, minus, times and divide."
 illustrated by Daniel Postgate and Rob Davis, and "The Murderous Maths of Everything", also illustrated by Rob Davis.
Goosebumps Series 2000 is a spin-off of the original Goosebumps series by R. L. Stine.
 The cover design of the "Series 2000" books was different from the original books, though the cover art was again by the same person, Tim Jacobus.
 There was no back tagline anymore, and the paragraphs at the back were excerpts from the book rather than a short summary of the story as the original books' back covers had.
 There was another difference with back covers too, as the "Reader Beware, You're In For A Scare!"
 of the original series was changed to "2000 Times The Scares!"
 and "Welcome to the new millennium of fear".
The Lives of Flemish, German, and Dutch painters refers to a compilation of artist biographies by Jean-Baptiste Descamps published in the mid 18th-century that were accompanied by illustrations by Charles Eisen.
 The list of illustrations follows and is in page order by volume.
 Most of the biographies were translated into French from earlier work by Karel van Mander and Arnold Houbraken.
 The illustrated portraits were mostly based on engravings by Jan Meyssens for Het Gulden Cabinet and by Arnold and Jacobus Houbraken for their "Schouburgh", while the work examples engraved in the margins of the portraits were mostly based on engravings by Jacob Campo Weyerman.
Jacobus Theodorus (Jakob Dietrich), called Tabernaemontanus (1525 – August 1590) was a physician and an early botanist and herbalist, the "father of "German botany" whose illustrated "Neuwe Kreuterbuch" (1588) or "Eicones Plantarum" (Frankfurt, 1590) was the result of a lifetime's botanizing and medical practice.
 It provided unacknowledged material for John Gerard's better-known "Herball" (London, 1597) and was reprinted in Germany throughout the 17th century.
 His Latinized name represented a translation of his native town, Bergzabern (literally ‘mountain taverne’) in the Palatinate.
 Tabernaemontanus began as a student of the pioneer of Renaissance botany, Hieronymus Bock.
