Hugh Howey..2011....someone asked ...Why is the book called wool?

Q. Here's my guess for the WOOL acronym. In book five, when Lukas is talking to Sil0 1 he's welcomed to “Operation Fifty of the World Order”. The Roman numeral for fifty is “L”, so the acronym would be “World Order, Operation L”.

Apparently a popular series. Tks for sharing.

Looks like an interesting series.....

Silo is a series of post-apocalyptic science fiction books by American writer Hugh Howey. The series started in 2011 with the short story “Wool”, which was later published together with four sequel novellas as a novel with the same name. Along with Wool, the series consists of Shift, Dust, three short stories and Wool: The Graphic Novel.[1]

Looks like there are now 9 books in the series.

Adding to my list of future reading.

Thanks TADSLOS!
