To mark the founding of the Insel-Bücherei 100 years ago, the complete bibliography of all volumes ever published in this legendary series is now available: all variants, all books published in both the West and East of divided Germany, and all bibliophile editions, compiled based on a review of the published works. A register lists all authors, editors, illustrators, translators, and writers of forewords and afterwords. The bibliography, produced in accordance with the aesthetic and typographic standards of the Insel-Bücherei, is thus an indispensable compendium for the literary and intellectual history of the past 100 years and also an essential reference work for readers of the Insel-Bücherei and those who wish to become one.
