Based on data provided by the San Francisco Public Library, The Chronicle compiled a list of the most borrowed books in 2021.

The list includes national bestsellers, like “The Vanishing Half,” “The Midnight Library” and former President Barack Obama’s memoir “A Promised Land.”

But it also includes titles by Bay Area-based authors, like Bonnie Tsui’s “Why We Swim” and a collection of essays by local writers, “The End of the Golden Gate: Writers on Loving And, Sometimes, Leaving San Francisco.”

Here are the 20 most borrowed titles in each category. Those set in the Bay Area or by local authors have an asterisk (*).
