A codex manuscript is a written (not printed) work bound as a book. RBML’s codex manuscript collections include Western manuscripts in collections distinguished by subject, and non-Western works in Arabic, Persian, Turkish, Hebrew, Sanskrit, and other languages.
The western items are usually bound as codices. The non-Latin items are codices or palm-leaf style manuscripts or whatever format is appropriate to the time, culture, and use. Printed materials in these languages cataloged for our printed book collections are not listed here (although a few of these collections include some printed materials because of historical happenstance).
