More than 100,000 people have now used the new Library of Birmingham since it opened.
It has taken a little over a week since Malala Yousafzai officially opened the £189 milliom Library to achieve the milestone.
Organisers said the amazing level of excitement goes beyond early expectations and gives a massive head-start towards the target of three million visitors in the first year.
The 100,000th visitor was named as Graham Fletcher, from Bromsgrove, who came to the library to do some research.
He said: “The Library of Birmingham is the best library in Europe, and I’ve seen them all.”
About 12,000 people per day are passing through the doors to see the architecture, take in the stunning views from the rooftop terraces, browse the collections or simply enjoy the arts and entertainments on offer.
According to figures released, 4,343 people have also seen the restored historic Shakespeare Memorial Room on the ninth floor.
Library director Brian Gambles said: “We’re thrilled with the way the people of Birmingham have embraced their new Library. Since our opening last week, we’ve been packed with excited visitors, some of whom have never set foot in a library before, eager to become a member and join in the celebrations.
“The Library of Birmingham is a proud and bold statement of belief in the power of learning and a new symbol for the city that will become known around the world.”
The city can also claim to be delivering on its pledge to improve education and literacy with 2,325 new members for library service and 10,285 books borrowed in the first seven days.
As well as attracting thousands of visitors the library has also received television coverage around the world.
On Wednesday night it was the subject of a special Culture Show programme on BBC2.
