Wolf Pup Books publishes bilingual (dual language) e-books.   The catalog consists of a wide range of bilingual titles by eminent authors. The three broad categories under which authors are published include French, German, and Italian. Through original text and English translation formatted optimally for e-readers and mobile devices, as well as desktop e-reading software, Wolf Pup Books gives easy access to the classics in fiction and nonfiction.

Published authors include Alexandre Dumas, Alphonse Daudet, Anatole France (Nobel Prize winner), Denis Diderot, George Sand, Gustave Flaubert, Guy de Maupassant, Honoré de Balzac, Jean Baptiste Racine, Jean-Jacques Rousseau, Jules Verne, Molière, Pierre Corneille, René Descartes, Victor Hugo, and Voltaire.

Authors include Friedrich Schiller, Grimm Brothers, Hermann Hesse (Nobel Prize winner), Johann Wolfgang von Goethe, Thomas Mann (Nobel Prize winner), Johanna Spyri, Sigmund Freud, Rainer Maria Rilke, Friedrich Nietzsche, Immanuel Kant, Heinrich Heine, E.T.A. Hoffman, Karl Marx, and Franz Kafka.

Authors include Dante Alighieri, Giovanni Boccaccio, and Carlo Collodi (pen name for Carlo Lorenzini).

The formatting of the text is optimized for e-readers. Each translated paragraph follows a paragraph in the original text. Paragraphs are almost always broken down into smaller chunks for easier reading and comparison of the original with the translated text.

To make the distinction easier, the translated text is given in cherry color, which is rendered as a lighter gray in monochrome readers.
