Not even close. The HP books were instant successes globally, publishing houses around the world couldn’t get them translated fast enough to meet expectations. They were sold out within days or even hours in many places. None of the classics had that kind of extended success because the world wasn’t working that way and there were infinitely fewer literate people with an interest in their fiction.

Another book series that got a similar reaction from readers (although from a lot fewer) was the Millenium trilogy.

But the thing with HP is that it appealed to children, YA, and grownups. And both to boys and girls.
