Blood tables: it is a holy action to kill Rosas is an 1843 Argentine libelle written by José Rivera Indarte against the governor of Buenos Aires, Juan Manuel de Rosas. It details 465 purported crimes committed by Rosas or the Popular Restoring Society; later editions increased the number by 22,560. The book was used as a primary source by the early historiography of Juan Manuel de Rosas; modern historians consider its figures to be inflated.

Handbuch des Schachspiels is a chess book, first published in 1843 by Tassilo von Heydebrand und der Lasa. It was a comprehensive reference book on the game, and one of the most important references on opening theory for many decades. The Handbuch had been the project of Paul Rudolf von Bilguer, who was with von der Lasa a member of the Berlin Chess Club and the influential group of chess masters later called the Berlin Pleiades. Bilguer died in 1840, with the work still in the early stages. Von der Lasa completed the project and saw it published, with his friend von Bilguer alone named as author. It contained comprehensive analyses of all opening variations then known, plus a section on the history and literature of chess.

A separate article of about six pages, containing an image, a description, and an account of worldwide distribution, together with reports of behaviour, is provided for each species.
