Khizana Beta

Bibliotheca Arabica's Reference Work on the Arabic Manuscript Tradition

Khizana aims to be a comprehensive bio-bibliographical reference work on agents and works related to Arabic manuscripts, focusing on the period between the 12th and the 19th centuries CE. As a reference work on Arabic literature, it integrates sources relevant to Bibliotheca Arabica. The most important source types are:

  • data from manuscript catalogues (print & online)
  • data from biographical and bibliographical works and
  • manuscript notes on owners, readers, etc.
Using graph based technologies, special emphasis is laid on providing evidence (i.e., provenance) for every piece of information. Work on the

Khizana will be expanded continuously in the next years. Currently, the following entries are available (including possible duplicates):









 General Remarks

Domain Model
The main entity types are currently person, work, manuscript and manuscript noteplace will be implemented at a later date. The entities are linked to each other and take on corresponding roles, e.g. a person can take on the role of an author, owner, scribe, etc. Our domain model is subject to continuous enhancement.
Entry Cards
Each entity type (person, work, manuscript, manuscript note) has got its own entry card. In the process of data integration, entities are becoming more and more linked to each other. These internal links are made visible by text highlighting.

Person: ابن أبي اللُّطْف
Factoid Provenance
Each piece of data is evidenced by one or more sources. The provenance buttons appear as soon as you hover over an entry. They look this:

The provenance may include more than on element, i.e. a chain of sources. This is the case when a source explicitly refers to another source, and we have reconstructed this chain in a machine-readable way.
The figurative mark of our logo is inspired by a bookshelf in the library of the Ottoman scholar and judge Saʿdī Celebī Efendī (d. 945/1539), illustrated in ʿĀshiq Celebī's Mashāʿir al-shuʿarāʾ, MS Millet Ktp., Ali Emiri Efendi, Tarih, n. 772, fol. 418v.
Machine Readability
The primary goal of our data integration efforts is to create standardised, machine-readable data, not complete reproductions of catalogue information. Among other things, we atomise data, e.g. we extract personal names from biographical records, automatically convert them to Arabic, and add Linked Open Data, such as missing information in the Hidjri calendar format.
Mistakes/ Data Artefacts
Due to the high proportion of automatically processed data, artefacts may occur that are immediately apparent to a human observer. We cannot correct all of them manually, but we prioritise those that occur regularly and can therefore be corrected automatically. Our research platform is also a test lab where making mistakes is part of the learning process.
Manuscript Notes Notation System*
used by B. Liebrenz
[   ] loss of text due to destruction (intentional or material damage)
(   ) illegible or unsure. Exception: fractions in prices, e.g. “(ثلث)”
< > subsequent addition or insertion
... omission (used in colophons)
* This system was followed increasingly over the years, but early usage may vary.
Script The default script (writing system) of our data is Arabic. Romanisation (LC, IJMES) may yield additional results. We are working to ensure that searches in Arabic script return all results, but this is a work in progress.
Results As the data is only partially authority controlled, the list of search results may contain several hits for the person or work you are looking for. Automated authority control, i.e. virtually merging identical entities, is one of our main tasks for the coming years.
Advanced Search Additional search functions will be implemented as soon as a sufficient amount of standardised and authority controlled data is available.
Sources & Data Resources
We are integrating data from manuscript catalogues (print & online), bio-bibliographical reference works as well as manuscript notes on owners, readers, etc. Data from other sources, such as historical catalogues, is also integrated wherever possible. The focus is on Arabic-language manuscripts, with Persian and Ottoman-Turkish manuscripts considered where possible. So far, data from the following sources have been integrated:

We are constantly refining our data in terms of quality assurance, machine readability, authority control, etc. These data enhancements, along with application updates, are released approximately every two months. Data generated from new sources is published at least once per year at the end of Q4, if possible, an additional update is realised at the end of Q2. There is currently no automated workflow for regularly updating data when taken from agile databases.
Our long-term goal is to make long-term relationships visualisable in order to be able to generate and verify research theses. However, this requires more data from more sources as well as their integration, atomisation, standardisation and linkage. We are still at the very beginning here — see the preview of the “raw” network graph at each entry.
