Jewish Book Month has been celebrated the month before Chanukkah since 1940. When I think about Jewish books, one institution that comes to mind is the National Yiddish Book Center, and its founder Aaron Lansky. The photo above is from my visit there in 2003.
From the Center's website:
"In 1980, when Aaron Lansky issued his first public appeal for old Yiddish books, it was estimated that only 70,000 Yiddish volumes were extant and recoverable. He rescued that many within six months. Today the National Yiddish Book Center’s collection totals over a million volumes, with the core collection stored in our state-of-the-art repository and 11,000 titles available online from our Virtual Yiddish Library. The Book Center also sponsors public events, internships and a wide range of cultural and educational programs designed to 'open up' the treasures of Yiddish culture for a new generation."
