The following online bibliography was started by Viktor Frankl himself and was kept up to date as far as possible after his death. More recently, the number of publications on Logotherapy and Existential Analysis has grown so much that a comprehensive bibliography can no longer be maintained. An exception are the Books by Viktor Frankl, whose reprints and translations continue to be listed and updated.
The lists given below represent the status of the Bibliography at the end of the year 2017. To search for more recent literature, we recommend the use of tools such as Google Scholar, MS Academic Search, BASE, iSeek or Academic Index.
