Start with the original records.
PEN America’s book-ban indexes organize school restrictions by reporting period. Consult the relevant year and title. Incident counts can include multiple restrictions affecting the same book; they are not counts of unique titles.
The American Library Association explains challenges and bans. The Great Falls College library’s challenged classics guide provides context for our featured authors.
Historical records are not live status trackers.
Notes on this site preserve the existing curated list’s historical references. A source index is a starting point for examining a title, not proof that a restriction continues today. Check the cited record and current institution information before describing a ban as active.
Two examples of why precision matters.
PEN America’s Duval County account includes a subsequent clarification about books kept off shelves during review. The ACLU’s account of The New Jim Crow explains that the New Jersey prison restriction was reversed.
Reading the statistics.
