The concept of a single volume containing multiple complete books is a well-established practice, often seen in collected editions or omnibus formats. These compilations typically gather related works, such as a series of novels by the same author, or themed anthologies curated around a specific genre or topic. An example would be a single volume containing all five books of a popular fantasy series.
Collecting multiple books into a single volume offers several advantages. It provides convenience and portability, allowing readers to carry an entire series or collection without the bulk of individual books. It can also be more economical, often costing less than purchasing each book separately. Historically, combining related texts has facilitated the preservation and dissemination of knowledge, as seen with early religious and philosophical compilations. Furthermore, the presentation of related works in a single volume encourages readers to engage with the broader narrative arc or thematic connections between individual texts.
