Dan Robinson (@bookmandan.bsky.social) Retired. Interested in just about everything. Avid reader.

Buy a book.

Any book, it doesn't matter which. The one you've been looking forward to, the one with the title that made you laugh, the weighty award-winner you've been meaning to get to. Whatever.

Treat yourself. Step away from it all. In this time of gross ignorance & madness, read something.

Texas bill could punish bookstores for 'obscene' books A new bill in the Texas Legislature, authored by Rep. Nate Schatzline, would allow businesses to be held liable if a minor reports damages from "obscene" books.

It was never just about schools, it was never just about libraries, and it isn't actually about the books.
