In 2014, Samantha Schoech, a writer and former bookseller, helped change the storyline for California bookstores.

Tired of the “doom and gloom narrative” that imagined the book business tanking, Schoech says she was motivated to help launch Independent Bookstore Day.

“We wanted a fun, celebratory way to talk about bookstores,” Schoech says of the event modeled on Record Store Day (April 22) and Free Comic Book Day (May 6).

Independent Bookstore Day takes place on the last Saturday in April and features author visits, live music, readings, scavenger hunts and limited-edition books. This year, Long Island’s Turn of the Corkscrew Books & Wine in Rockville Centre, The Dolphin Bookshop & Cafe in Port Washington and BookHampton in East Hampton are all participating.

Independent Bookstore Day was originally the brainchild of Pete Mulvihill, co-owner of Green Apple Books in San Francisco. Since its inception, Schoech has produced the event and been integral to its national growth.

In its inaugural year, 95 stores participated. On April 29, more than 490 bookstores nationwide will take part.

Author Emma Straub (“Modern Lovers”), who is opening a bookstore in Brooklyn, is the “ambassador” for this year’s event. “Independent bookstores are my first stops in any new city,” Straub says. “They are ports in the storm, passageways to magical lands, escape hatches out of bad moods.”

Among the items for sale at participating bookshops are original prints by Jenny Lawson (“The Bloggess”) and “A Literary Cocktail Party: Favorite Drinks from Our Favorite Others,” a collection of cocktail recipes from contributors such as Straub, Edan Lepucki (“California”) and Viet Thanh Nguyen (“The Symphathizer”).

Here’s what else you can expect Saturday at Long Island’s participating stores:
