David Jones was started by David Jones, a Welsh merchant who met Hobart businessman Charles Appleton in London. Appleton established a store in Sydney in 1825 and Jones subsequently established a partnership with Appleton, moved to Australia in 1835, and the Sydney store became known as Appleton & Jones. When the partnership was dissolved in 1838, Jones moved his business to premises on the corner of George Street and Barrack Lane, Sydney. David Jones claims to be the oldest department store in the world still trading under its original name.

When auto-changing turntables were commonplace, records were typically pressed with a raised (or ridged) outer edge and a raised label area, allowing records to be stacked onto each other without the delicate grooves coming into contact, reducing the risk of damage. Auto-changers included a mechanism to support a stack of several records above the turntable itself, dropping them one at a time onto the active turntable to be played in order. Many longer sound recordings, such as complete operas, were interleaved across several 10-inch or 12-inch discs for use with auto-changing mechanisms, so that the first disk of a three-disk recording would carry sides 1 and 6 of the program, while the second disk would carry sides 2 and 5, and the third, sides 3 and 4, allowing sides 1, 2, and 3 to be played automatically; then the whole stack reversed to play sides 4, 5, and 6.

Hume and other Scottish Enlightenment thinkers developed a 'science of man', which was expressed historically in works by authors including James Burnett, Adam Ferguson, John Millar, and William Robertson, all of whom merged a scientific study of how humans behaved in ancient and primitive cultures with a strong awareness of the determining forces of modernity. Modern sociology largely originated from this movement, and Hume's philosophical concepts that directly influenced James Madison (and thus the U.S. Constitution) and as popularised by Dugald Stewart, would be the basis of classical liberalism.
