The stack is high: There are now some 3,500 titles in Reclam's Universal Library ("Universal-Bibliothek") series of literary classics, including many by famous German writers and artists (above). But let's not kid ourselves: Who honestly managed to read more than 100 during their studies?

Each German household probably holds more of these little books than meets the eye. They're so small that they easily disappear behind larger volumes.

Along with the yellow booklets in German, there are the orange bilingual volumes, while the red ones are in a foreign language, and the the blue ones offer study guides to accompany the literary works.

Scribbled and stained covers can be found on many well-loved, or at least well-used, Reclam volumes. It's more proof that these books didn't just sit on a shelf.

Some authors' names might trigger nostalgia or chills, but they all have a home in the Reclam format.

Reclam publishes more than just the classics of literature. Speeches, theories and other essays are also included in the series, such as this book of three speeches by contemporary German political activist Jan Philipp Reemtsma.

Reclam includes books that every student should read, including "The Diary of Anne Frank."

Scribble, doodle and scrawl: Whatever helps when a class is really boring. The notes of long ago can make for interesting reads on top of the book — literally.

Penguin Classics were first created 80 year ago. Acclaimed graphic designer Willy Fleckhaus definitely drew on the original Reclam model for the covers he designed for German publisher Suhrkamp (above right).

If thick, expensive tomes can turn off prospective readers, the Reclam books' low cost added to their enduring popularity.

A giant of German children's lit, Otfried Preussler wrote for kids aged six and up. "The Little Witch" tells of a girl learning the hard way what it means to be a "good" witch. In "The Robber Hotzenplotz," a man steals a grandma's coffee grinder - and two boys set off to capture him. This tale also features the wizard Petrosilius Zwackelmann. Say his name aloud - that's the kind of story this is.

If the movie "The NeverEnding Story" thrilled you during your youth, you can - like the hero of that tale - immerse in Michael Ende's masterpiece that inspired the film. Following the movie's success, his other works were also translated. "Momo" deals with time - and criticizes efficiency and stress. "Jim Button and Luke the Engine Driver" is a beloved classic of German children's literature.

In "The Trip to Panama," a bear and a tiger lead a dreamy and lazy life - until a wooden crate comes floating on a nearby river. "Panama" is written on it, and it smells like bananas. Intrigued, the bear and tiger set off to find this wonderful smelling country. Their long and winding quest leads them to the best place on Earth: home. Janosch's imagery and surreal logic charm young and old alike.

A well-known little dinosaur in Germany, the urmel, hatches from an egg in "Urmel From The Ice." The story is one Max Kruse's most famous works, thanks to its TV adaptation by the Augsburger Puppenkiste (picture). It also inspired the animated film "Impy's Island." The author's other famous work, "Lion on the Loose," is a merry adventure following an escaped wild animal through the city.

Each of the main characters remains a safe distance away from evil in "When Hitler Stole Pink Rabbit" (1971), by Judith Kerr. It is told through the eyes of a nine-year-old, Anna, whose family flees Germany just as the Nazis take power. There is no war in this novel; it hasn't happened yet. But the story remains as relevant today as it ever has been: By the end, Anna and her family are refugees.

Heading to Berlin? Pick up a copy of "Emil and the Detectives" by Erich Kästner. It'll take you (and your children) back to the German capital as it was in the late 1920s. After that, try another of Kästner's stories: In "Lottie and Lisa," separated twin girls meet each other for the first time at a summer camp. Decades later, it was adapted to the 1998 Hollywood blockbuster "The Parent Trap."

Many kindergartens and primary schools in Germany are named "Max and Moritz" after the prank-pulling duo in Wilhelm Busch's classic book. Note, however, that the book's pranks - and its moral compass - are firmly set in 1865. One example (spoiler alert!): After the boys' final prank fails, the two are ground up into pieces and fed to ducks. That's it. The end. No sequel.

Another sure way to traumatize your kids is "Struwwelpeter." In two of these 10 "moral" stories, a child dies; in another, a kid's thumb is cut off. At least some of the stories are lighter. One involves "Fidgety Philipp," whose dinner table antics spoil every meal. Even 150 years later, his name is used to scold children who can't sit still: "Don't be such a Zappel-Philipp!"

The "Inkheart" trilogy was published in the midst of the "Harry Potter" hurricane but still went on to become a success. Set in contemporary times, Cornelia Funke's main character in the story, a 12-year-old named Meggie, has the ability to take things out of books and make them come to life. It's something of a family trick. But it wouldn't be a good story unless that power came at a price.

Zamonia is a fictional continent where funny stories happen - and the name of a series by Walter Moers. "The 13 1/2 Lives of Captain Bluebear" is a good introduction, but it's OK to start with the fourth book, "The City of Dreaming Books." Often, the author describes a character, waits a while for the mental picture to cement, and then - surprise! - unveils a wacky illustration of his creation.
