Index Theologicus

Its predecessor, the Zeitschrifteninhaltsdienst Theologie ("Theology Journals Content Service") or ZID, was started in 1975.Weisweiler, Hilger. "[https://digital.zlb.de/viewer/readingmode/019591853_1996/116/ Der Zeitschrifteninhaltsdienst Theologie der Universitätsbibliothek Tübingen]". Bibliotheksdienst 30(2), 1996, pp. 243-251, doi:[https://doi.org/10.15496/publikation-34164 10.15496/publikation-34164] (in German).{{rp|243}} This was a current content service which reprinted the table of contents of the main theology journals; monthly ZID issues included an index of authors, Biblical references and persons, which were later combined in an annual and a five-year index.{{rp|243}}

In 1994-1995, the ZID was converted into a database using allegro-C (a library software developed by the Library of the University of Braunschweig); the bibliographic data extracted from the journals was now stored electronically before it was published in the ZID issues, and the data which had been published in the prior ZID issues was retrospectively catalogued.{{rp|245f}} In addition to subject indexing with standardized index terms, a faceted classification with 130 classes was introduced at that time.{{rp|246}}

The database itself was made available to the public in German first on floppy disks, later on CD-ROM.Becht, Michael. "[https://digital.zlb.de/viewer/readingmode/019591853_2005/1113/ 30 Jahre Dokumentation theologischer Aufsatzliteratur. Jubiläum in Tübingen]". Bibliotheksdienst 39(8/9), 2005, pp. 1116-1132, doi:[https://doi.org/10.15496/publikation-34145 10.15496/publikation-34145] (in German).{{rp|1121}} Starting in 2001, the subject headings and the user interface were also translated into English.{{rp|1122}}

At the end of 2000, the ZID ceased the publication of its print version. The name of the database was changed to Index Theologicus in 2002, when the publishing house Mohr Siebeck started managing its distribution.{{rp|1123}} Since 2007, the database is only available online and free of charge.Kim, Timotheus Chang-whae & Zumstein, Philipp. "[https://edoc.hu-berlin.de/bitstream/handle/18452/9745/kim.pdf?sequence=1&isAllowed=y Semiautomatische Katalogisierung und Normdatenverknüpfung mit Zotero im Index Theologicus]". LIBREAS. Library Ideas 29, 2016, pp. 47-56 (in German).{{rp|47}}

As of July 2022, IxTheo comprised over 4 million records on theological literature (including monographs and articles), and about 15,000 records are added each year.Dörr, Marianne. "[https://liberquarterly.eu/article/view/10823/11730 Open Access Information Service for Researchers in Theology]". LIBER Quarterly 28(1), 2018, pp. 1-9.{{rp|5}} Subject headings and search capabilities are provided in 9 languages: English, German, French, Italian, Spanish, Portuguese, Greek, Russian and Chinese.{{rp|7}} A special search capability for specific Bible passages using standard abbreviations is also available.{{Cite web|url=https://ixtheo.de|title=Search for Bible passages|website=ixtheo.de|language=en|access-date=2019-02-26}}

The faceted classification (named "IxTheo classification") now comprises 139 classes divided into 13 main groups.{{Cite web|url=https://www.ixtheo.de/IxTheoClassification|title=IxTheo-Classification|website=ixtheo.de|language=en|access-date=2019-02-27|archive-date=2018-11-30|archive-url=https://web.archive.org/web/20181130202332/https://www.ixtheo.de/IxTheoClassification|url-status=dead}}

Since 2013, IxTheo uses the database of the regional cataloguing network "Südwestdeutscher Bibliotheksverbund" (SWB, in south-western Germany), which is shared i.a. by the theological faculties of Tübingen, Heidelberg and Freiburg.{{rp|2f}}{{rp|49}} The data from the former allegro-c database (over 500,000 records) was migrated into the SWB catalog in 2016.{{rp|49}}

Since 2015, IxTheo has been managed and further developed by the "Fachinformationsdienst/FID Theologie" (a "specialised information service" in theology) thanks to grants from the German Research Foundation ("Deutsche Forschungsgemeinschaft" or DFG).{{cite web |language=de |url=https://wikis.sub.uni-hamburg.de/webis/index.php/Theologie |title=Theologie – Webis |access-date=2019-01-03}}

IxTheo is implemented as a faceted Discovery System built on the VuFind library search engine.{{rp|3}} A growing number of journals are processed using semi-automated production procedures with software such as ImagewareFassnacht, Martin & Gebhard, Winfried. "[https://www.b-i-t-online.de/heft/2016-06-nachrichtenbeitrag-fassnacht.pdf Index Theologicus - neue Produktionsverfahren bei der Bibliographieerstellung]". b.i.t.online 19(6), 2016, pp. 511-514 (in German). and Zotero.{{rp|49–53}}{{rp|4}}
