Objective: Researchers have paid attention to illustrated manuscripts in order to study their images. Therefore, it is necessary to include reliable information about these images as a catalog. This research tries to show the CCO method efficiency for cataloging the illustrations of pictorial manuscripts (case study: Qazvini's Aja'ib al-Makhluqat (The wonders of creatures)) and shows the appropriate components for preparing a valid and accurate catalog for pictorial manuscripts. One of the important goals of this article is to introduce the CCO method and how to use its components in documenting the images of visual manuscripts.
Research/ Method approach: This research was carried out in a descriptive-analytical method, and library reference sources were used to explain terms and explanations of words.
Findings and Conclusions: In this research it was shown that the specialized information of visual manuscripts can also be cataloged. Catalogs can be designed in two ways; present the entire work in the form of a catalog; or introduce each of the pictures separately in the catalog. The findings show that in the cataloging of the two paintings “Wak Wak” tree (talking tree) and “Harut and Marut”, (Two angels in Islamic tradition), things such as class, work type, title, creator, subject (general and specific), location (current and original), sizes, style, description and related images can be accurately cataloged using controlled vocabularies. Regarding some components (such as style) in the field of Islamic painting, complete research has not been done yet; Therefore, the cataloger should have relative familiarity with these research areas. Also, in cases such as "Description" values, i.e., the description mentioned in the manuscript’s text, the rewriting and reading of this part of the visual manuscript can be done with the help of manuscript experts familiar with the scripts of the Islamic era. Therefore, the cataloger should have relative familiarity with the codicology. In addition, another important result of this research is the related images documentation to each painting for the use of art researchers. The results of this research can be used for iconographic research. Also, the findings of this research show that there are many photo manuscripts kept in libraries and museums around the world, that each of these copies can be cataloged using the CCO method, and in the next steps, by digitizing the catalogs, they can be made available to the public.
