However, you could consider these less common terms, depending on the context:
* "Book supports" is a more technical term.
* "Book stoppers" emphasizes their function.
* "Literary anchors" is a more poetic option.
Ultimately, the best term depends on your specific needs. If you're writing a book review, "bookends" is probably the best choice. If you're writing a product description, "book supports" might be more appropriate.
