The Husserliana is the complete works project of the philosopher Edmund Husserl (April 8, 1859 – April 27, 1938), which was made possible by Herman Van Breda after he saved the manuscripts of Husserl.
The Husserliana is published by the Husserl Archives of the Higher Institute of Philosophy of the Catholic University of Leuven.
It is often referenced in secondary literature using the abbreviated title Hua followed by the appropriate volume number.
Volumes contain both previously published books and articles in a critical edition as well as selections from unpublished manuscripts conserved at the Husserl-Archives Leuven.
Important publications in the Materialien have been Husserl's lectures on logic from 1896 and on Urteilstheorie (theory of judgment) from 1905.
