So, there's this website which will calculate how long it's going to take for you to read your TBR pile - now, this is based on the idea that a) I don't add anything else to it in the meantime (so unlikely a possibility as to be immeasurable with the naked eye) and b) that I continue to read at a consistent rate of approx. 5 books a month:
Reading all 210 books will take:
3 years and 6 months
You will finish your TBR pile on:
March 2, 2019
Thanks to Libromancer's Apprentice for the link and resulting entertainment!
