“Ephemera: Collectable items that were originally expected to have only short-term usefulness or popularity. – OxfordDictionaries.com”
From this page you can find links to items on the Blog that you might have missed. There are some interesting things here, so it is well worth a browse through the ephemera.
I have lots more to add, so keep checking back, and if you find anything of interest, please make a comment on the Blog (scroll to the foot of this page).
