The Index Theologicus (IxTheo) is an international scientific open access bibliography for theology and religious studies.
[1][2] It covers scientifically relevant information on Christianity as well as on dialog with other religions from all confessions, in several languages and media types and throughout history.
The name of the database was changed to Index Theologicus in 2002, when the publishing house Mohr Siebeck started managing its distribution.
[7]: 5 Subject headings and search capabilities are provided in 9 languages: English, German, French, Italian, Spanish, Portuguese, Greek, Russian and Chinese.
