This goal has the following fine print specified by shanaqui:
The definitive list is the one in my Notetab file: anything not entered there doesn't count, and it's from that I take the current total. Any new books must be added both to that and to the total here; I want a net reduction in my TBR, not just a reduction of my backlog as it stood on the start date, 15/04/2018.
It is also legit to "flee" a book I don't plan on finishing or no longer plan on reading.
A rough glance at what I should be reading can be obtained from https://breathesbooks.com/ under the "Mount TBR" menu.
A derail is always not-legit if it is due to books being bought FOR me.
