Writer and novelist Khalid bin Ahmed Al-Yousef continues his systematic effort to track literary works in the Kingdom of Saudi Arabia and to introduce its writers—including authors, poets, novelists, short story writers, and critics—along with their works, documenting them in reference guides and compendiums. This is a distinctive cultural undertaking that he has carried out single-handedly for over 35 years. This new volume, titled *Dictionary of Saudi Writers* (Mu‘jam al-Udaba’ al-Sa‘udiyyin), is the most extensive dictionary on Saudi writers published by Khalid Al-Yousef. Released by Al-Intishar Al-Arabi Foundation in Beirut and Sharjah (1447 AH / November 2025 CE), the work spans 720 pages, covers a period of 150 years, and includes biographies of 1,544 writers. It is a specialized biographical dictionary dedicated to Saudi writers, providing a brief profile for each. It encompasses writers with published creative literary works, as well as those with published material across various print media—even if they lack a standalone printed book—and includes scholars, critics, and historians of Saudi literature. The book profiles Saudi writers who lived through and witnessed the early days of the Kingdom of Saudi Arabia—a status confirmed by consensus among reference sources. Khalid Al-Yousef describes the work as a project designed to be comprehensive and all-encompassing; no one was excluded unless they chose not to participate, thereby assuming responsibility for their absence from the volume. Al-Yousef adds: "In 1412 AH (1992 CE), I was commissioned to develop the *Saudi Writers’ Directory*. Three years later, I published *Directory of Male and Female Writers*—a biographical work covering living writers active in the literary and cultural spheres. That directory became the primary reference for researchers in the field. Fifteen years later, I published an anthology of the short story in Saudi Arabia. Beyond featuring outstanding short story texts, that book provided new, focused biographical profiles for every participating author." After examining dozens of books that... Having reviewed existing publications in this field, I recognized the need to compile a comprehensive dictionary of Saudi writers. Previous works were often limited to writers from a single region, suffered from partiality or imbalance in their biographical entries, omitted a vast number of authors, or focused exclusively on specific literary genres. Consequently, I undertook the creation of this dictionary starting in 1435 AH (2014 CE). I adopted a systematic, scholarly approach for each entry, which includes: the writer’s full name (four-part name); their professional or pen name; place and date of birth; highest academic degree (including specialization, awarding university, and graduation date); a brief literary profile (approximately four lines) highlighting their literary attributes and notable activities; and a list of six selected works (for authors with a larger bibliography), specifying the genre and publication date. These details—essential to the writer's literary identity—are limited to seventy words per entry. The dictionary comprises a detailed introduction covering its content, the history of biographical and prosopographical writing in the Kingdom, and the author’s journey in compiling the work. This is followed by an index of male and female writers—arranged by professional name with corresponding serial numbers for easy access—the biographical entries themselves, and a list of references and sources. This dictionary reflects Al-Yousef’s commitment to tracking, compiling statistics on, and documenting literary works in the Kingdom, as well as his enduring interest in annotated bibliographies and the documentation of Saudi literary publications.
