- investigate Girtab nomenclature
- There seems to be some confusion regarding this name. Jim Kaler of STARS says Girtab refers to Theta Scorpii. This is also indicated in the sidebar of the Theta Scorpii Wikipedia article. However, Wikipedia also says Girtab refers to Kappa Scorpii.
- American Civil War (en.wikipedia.com)
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union (“the North”) and the Confederacy (“the South”), which had been formed by states that had seceded from the Union. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which many believed would place slavery on a course of ultimate extinction.
