Recently in my timeline, I have seen users that have repeat posts from earlier such that it is in the format of a reblog. 





When I click on my posts I do not see the option to reblog.

How to reblog oneself on Tumblr ?


Question: Is there a word specifically referring to the stand upon which a large book is displayed, opened to a page?
Answer: Various terms are used:

Book cradle of book exhibition cradle (source, source) are used for museum displays.

A tradename for a purportedly superior book cradle is the Benchmark Butterfly Bookmount. (source)

A search of book cradle shows that book stand (mentioned by nxx) is also used, apparently for less demanding displays.
