Appendix slides; Text boxes; Handouts. You can prepare a detailed document to leave behind as a handout after your presentation. Rather than inundating your audience with all the minutiae of your topic in your slides (i.e., charts, tables, diagrams, etc.), you can focus your PowerPoint presentation on the most salient points.
Nevada Admitted to Union, 1864. Nevada was admitted to the Union, October 31, 1864, being the thirty-sixth in the sisterhood of States. In area she comprises an imperial domain, being almost as large as England, Ireland, Scotland and Wales combined.
Among other things, it ensured that [Nevada's] riches would help the Union and not the Confederate cause. And interestingly, it was Nevada's mine operators themselves who led the drive for Nevada statehood in 1863, at a time when Nevada's economy was relatively robust. The miners' chief motive was primarily economic.
