It's likely your library has put up a book display or list related to Black History Month. If you look at the official US government site and review the exhibits page, you will see a huge variety of topics. There are exhibits on educators, visual artists, theatre, dress, folklife, colleges, literature, music and religion. Use these exhibits as a place to start your own displays and lists for Black History Month.
In addition to displays focusing on slavery and the Civil Rights Movement, use this month to introduce patrons to titles in your collection that can allow them to see parts of Black history that they might not be familiar with. There are topics like the Harlem Renaissance , Black cowboys, Black entrepreneurs, Black scientists, and more. GLAAD has information on Black LGBTQ history. Don't forget to see what your local history collection has about history in your city, state, or region.
The most popular display I have ever put up in February was related to Black chefs, cooking, and history of food in Black culture. In less than a week, the display was empty, after being filled several times. Another popular display was biographies and memoirs. Choose a variety of people from many backgrounds and experiences. Use those faceouts to show the depth and breadth of Black history.
Fiction is something that sometimes gets ignored. Use a display of mystery, romance, science fiction, or romance to bring out your backlist and give it some light. There are plenty of lists you can start with online:
BookRiot has 24 Black romance books add to your TBR.
WOC in Romance has lists by trope and subgenre.
The Los Angeles Public Library published a list in 2018 of Black mystery writers and their Black detectives.
CrimeReads offers 25+ new releases from Black authors including mysteries of all kinds, thrillers, and suspense novels.
The Toronto Public Library posted a list celebrating Black speculative fiction authors.
Epic Reads has a YA focused list of science fiction and fantasy by Black authors.
Essence offers a beginner's guide to Afrofuturism.
The Root produced a list of titles by Black horror authors
Goodreads has this collection of horror and thrillers by Black authors.
The Horror Writers Association has a blog which features diverse authors all year.
Find interviews with authors, historians, artists and link to them on your social media. Include information about your online lists and collections. Don't forget your storytimes and youth events. Include a variety of books for youth of all ages in your displays. I haven't even mentioned things like graphic novels, movies, and music.
I will end with a reminder that if you don't have enough to put up a display on a particular topic, it is a good time to review your collection and see what should be added. Also, use diversity and inclusion in your book displays all year.
