Terminologia Medica Polyglotta (1979) by Georgi Arnaudov: a rare translated reference work (4th Edition, 944 pp., print run 40,200, no reprints). Dataset of ownership artefacts from the Uryvaevs' scientific library

Terminologia Medica Polyglotta (1979) is a rare translated edition from Bulgarian, a fundamental polyglot reference on medical terminology authored by Dr. Georgi D. Arnaudov and published in Sofia. The publication is positioned primarily as a rare translated reference work: the print run of the 4th edition amounted to 40,200 copies, with no subsequent reprints, and its poor representation in modern library holdings further underscores its bibliographic rarity. The total volume of the edition is 944 pages; the spine thickness is 6 cm (≈2.36 inches), which objectively attests to the high information capacity and the substantial scale of the terminological array systematised by the author. The scientific value of the publication lies in its multilingual structure, which enabled Soviet scholars to work effectively with international medical vocabulary, and in its status as a translated edition reflecting cross‑border scientific communication and terminology standardisation practices in the second half of the 20th century. As a rare reference source, Terminologia Medica Polyglotta records the established terminological equivalents of the period and serves as an important linguistic and historical testimony to the professional language practices of the era. This copy originates from the library of the spouses‑scientists Leonid Viktorovich Uryvaev, MD (1939–2026; Scopus ID: 7006016398; ORCID ID: 0000‑0002‑2556‑4924), and Irina Vasilyevna Uryvaeva, D.Biol. (1939–2020; Scopus ID: 7006010900). The book was actively used in the owners’ research and served as a reference source for writing major monographs and articles in English, functioning as a tool to ensure terminological precision and consistency in international‑level publications. Despite intensive use in research practice, the copy is in very good condition, with only slight paper yellowing and minor edge wear, confirming careful handling of the publication. Of particular value as an artefact of the material culture of science is the personal ownership bookmark in the form of a flower cut out from a greeting card. This item reflects individual practices of organising reference material and the emotional and personal relationship the owners had with the book as an important working tool. For objective metric assessment, the deposit includes photographs of the bookmark with a scale ruler. The deposit includes PDF files with a systematic photographic documentation of key elements of the copy: the title page and imprint (to confirm the uniqueness of the edition), the general view of the book, detailed shots of the flower‑bookmark (front and back, close‑ups of the cutting technique and paper texture, including images with a scale ruler), and images of use evidence (yellowing, edge wear, creases). Materials are structured by object type (edition overview, artefact‑bookmark, use evidence), enabling targeted analysis without the need to browse a full scan. The collection is suitable for quantitative and qualitative studies in material book culture, including classification of personal markers, wear pattern analysis, reconstruction of Soviet‑era research workflows, and examination of mechanisms for mastering multilingual professional vocabulary. The collection is intended for research in the history of science, book history, history of medical education, and language teaching methodology, as well as for educational use in lectures and seminars on the history of science and reference‑work practices. Original photographic images in JPG format are retained in the curator’s local archive; the repository hosts optimised PDF compilations suitable for viewing, citation, and reuse in teaching and research. The dataset includes calibration images, captured with a scale ruler under natural diffused daylight. The set comprises four images: cover dimensions measured along the length and width, and documentation of the ownership bookmark from both sides to record its size and condition. A 30 cm metal ruler with a millimeter scale was used as a calibration reference, placed parallel to the measured side of the object. Reflections on the ruler’s surface serve as an additional indicator of lighting conditions and allow researchers to assess potential geometric distortions. Files are marked with the "_calib" suffix and include explicit descriptors for the measured parameter (length/width) or artifact side (front/back) in the filename. This imaging protocol ensures measurement reproducibility and supports secondary analysis in studies of material culture, history of science, and book history. The dataset adheres to the FAIR principles. Works from the 1970s are considered to be in the public domain. The deposit showcases ownership artefacts and marks of use as historical evidence and is not intended for commercial distribution of the text.
