"Ich will ins Grenzenlose" - the first words of Else Lasker-Schüler's poem "Weltflucht" determine the title and topics of the XXIV Else Lasker-Schüler Forum in May 2023 - and thus the title of the 15th Almanac. The authors illuminate the boundless from different perspectives. Bazon Brock looks at the "horizons of art", Günter Verheugen looks at "border issues", Gerold Theobalt at "the last border", suicide. Astronaut Reinhold Ewald broadens our view into space and of the waste problems in orbit. Ingrid Bachér took notes on the war in Ukraine, Heiner Bontrup worked with young Ukrainians and Russians on the poetry project "Friendship in times of war." Also printed here are Özlem Genç's speech, given at the commemorative event 30 years after the arson attack on her family in Solingen, and the text of the theatre play "Grenzgang Rote Linien" by Herbert Mitschke, in which Rosa Luxemburg and Else Lasker-Schüler meet.
