If you're a bibliophile, Thursday is your time to shine: It's both World Book Day in the United Kingdom and Read Across America Day in the U.S.

World Book Day, a United Nations holiday celebrated in April in most places, is a chance to honor authors, illustrators and readers alike to appreciate books and all they provide, while Read Across America Day is a similar holiday centered around writer Dr. Seuss' birthday.

Whether you're observing the lit-focused days with costumes or green eggs and ham, you should get inspired to read. Start by checking out these quotes about books, collected from the Huffington Post and Goodreads:

“A room without books is like a body without a soul.” ― Marcus Tullius Cicero

“Sleep is good, he said, and books are better.” ― George R.R. Martin

“Sometimes, you read a book and it fills you with this weird evangelical zeal, and you become convinced that the shattered world will never be put back together unless and until all living humans read the book.” ― John Green

“If you don’t like to read, you haven’t found the right book.” ― J.K. Rowling

“Reading is the sole means by which we slip, involuntarily, often helplessly, into another's skin, another's voice, another's soul.” ― Joyce Carol Oates

“No entertainment is so cheap as reading, nor any pleasure so lasting.” ― Lady M. W. Montagu

“One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time.” ― Carl Sagan

“I read for pleasure and that is the moment I learn the most.” ― Margaret Atwood

“I love books. I like that the moment you open one and sink into it you can escape from the world, into a story that's way more interesting that yours will ever be.” ― Elizabeth Scott

“If there's a book that you want to read, but it hasn't been written yet, then you must write it.” ― Toni Morrison

“A book, too, can be a star, ‘explosive material, capable of stirring up fresh life endlessly,’ a living fire to lighten the darkness, leading out into the expanding universe.” ― Madeleine L’Engle

“Books are a uniquely portable magic.” ― Stephen King

“Everything in the world exists in order to end up as a book.” ― Stéphane Mallarmé

“The books transported her into new worlds and introduced her to amazing people who lived exciting lives. She went on olden-day sailing ships with Joseph Conrad. She went to Africa with Ernest Hemingway and to India with Rudyard Kipling. She travelled all over the world while sitting in her little room in an English village.” ― Roald Dahl

“The more that you read, the more things you will know. The more that you learn, the more places you’ll go.” ― Dr. Seuss
