Thomas A. Sebeok memorial library includes the total collection of biosemiotic literature (appr. 1000 volumes) that belonged to T.A. Sebeok (1920-2001). The collection has been transferred from Bloomington to Tartu in 2006.

The establishment of Thomas A. Sebeok memorial library in Department of Semiotics in Tartu is a natural and logical continuation of T. Sebeok's warm relations with Tartu University. The final arrival of the total collection of his biosemiotic literature (appr. 1000 volumes) was also supported by his widow Jean Umiker-Sebek, professor Alfred Strickholm and others. This historically valuable and significant collection of books is a necessary and worthy material for scientific research for anyone who studies semiotics in Tartu University.
Thomas A. Sebeok (1920-2001) was the leader of international semiotics for over 30 years. Sebeok began as a fenno-ugrian linguist (including mari language), but later his interests changed to non-verbal communication and from there to animal communication. He became one of the founders of zoosemiotics. He was active in various fields of semiotics, working also as an editor, among other publications, of a series "Approaches to Semiotics" (over a hundred volumes). Until his death he was the editor-in-chief of one of the main semiotics journals Semiotica (since its founding in 1969). He also proposed Juri Lotman as the co-editor of this journal and the vice president of the International Semiotics Association. Sebeok emphasized the importance of the Tartu semiotics school as conceiver of the conception of a sign systems as a modeling systems, also his writings brought attention to Jakob von Uexküll's theoretical works.
Sebeok was born in Budapest and studied in the University of Chicago. Throughout his life he worked in the Indiana University, Bloomington, where he lead the Center for Language and Semiotic Studies. At the center worked also two Estonian scholars - Felix Oinas and Alo Raun. Even today there is a lecturer of Estonian at Indiana University.
Sebeok visited Tartu for three times and his initiative laid the foundation for the International Association for Finno-Ugrian Semiotic Studies.
