"Harry Potter and the Deathly Hallows" doesn't hit bookshelves for five months, but many local libraries already have begun a waiting list.
Act fast and you might not have to wait long if you don't want to buy.
The Clark County Public Library is nearing 40 holds.
"It will build as it gets closer to the date in the summer," spokeswoman Allison Peck said.
Author J.K. Rowling announced on her Web site this month that the book would go on sale July 21.
About 250 patrons reserved the most recent Harry Potter book by its release date, Peck said.
The library got about 500 of those books but is unsure how many "Deathly Hallows" editions it will purchase, she said.
