The story Stanger linked to didn’t mention this, but Amazon has quietly launched a library distribution program. With their current distribution strength they could easily take over the market. Some librarians aren’t happy about this because Amazon is Amazon. But it’s the only force that could immediately scale up to replace a behemoth like B&T.
Although that article does talk about the decrease in library usage during Covid, my understanding is that the recent pressures on spending for the majority are driving people back to libraries as a free resource. And both federal and state funding for libraries have been dwindling for years. Higher usage is facing lesser availability. This is a crisis.
