Babies born on Saturday can get a free book thanks to Dr. Seuss' birthday.

Dr. Seuss Enterprises announced in February that it is honoring the author's legacy by giving away a free, personalized copy of "The Cat in the Hat" to every baby born in the U.S. on this year's Dr. Seuss Day.

The holiday is celebrated annually on March 2 to honor the late Theodor "Ted" Seuss Geisel, who was born on the day in 1904. Saturday will mark what would have been Geisel's 120th birthday.

The beloved children's book author wrote classics still present in classrooms and homes across America, including the classic "Cat in the Hat" (1957), "Green Eggs and Ham" (1960) and "Oh the Places You'll Go!" (1990).

Dr. Seuss Day coincides with Read Across America Day, established by the National Education Association (NEA) in 1998. Both celebrations are an effort to make reading more exciting for families and for kids.

Here's what to know about the free book giveaway.

'The Cat in the Hat':'Somewhere in between offensive and inoffensive'

'Cat and the Hat,' Dr. Seuss books controversy

The expansive and long-beloved collection of Dr. Seuss books has taken a cultural hit in recent years on racial insensitivity grounds, with six titles pulled by the Seuss gatekeepers in 2021, USA TODAY previously reported. The books pulled were:

• "And to Think That I Saw It on Mulberry Street" (1937)
• "McElligot's Pool" (1947)
• "If I Ran the Zoo" (1950)
• "Scrambled Eggs Super!" (1953)
• "On Beyond Zebra!" (1955)
• "The Cat's Quizzer" (1976)

As for "The Cat in the Hat," "the cat is somewhere in between offensive and inoffensive,” Philip Nel, Kansas State University professor of English and author of “Was the Cat in the Hat Black?: The Hidden Racism of Children’s Literature and the Need for Diverse Books,” previously told USA TODAY.

Nel said that telling aspects of the cat clearly are derived from racist blackface performers popular a century ago – performers, who, like the cat, often wore white gloves and neckwear. 

But Geisel also went out of his way during his long career to write stories that celebrated diversity.

Never-before-seen sketches by Dr. Seuss have been added to new books written and illustrated by an inclusive group of authors and artists, the AP reported.

The new line includes original stories matched with unpublished illustrations selected from archives at the University of California San Diego, Dr. Seuss Enterprises said in a statement.

The new line of Dr. Seuss books is expected to hit shelves this spring, according to a release by Penguin Random House.
