Folio Society in the context of "George R. R. Martin"

A slipcase is a five-sided box, usually made of high-quality cardboard, into which binders, books or book sets are slipped for protection, leaving the spine exposed. Special editions of books are often slipcased for a stylish appearance when placed on a bookshelf. A few publishers, such as the Folio Society, publish nearly all their books in slipcases.

Protective slipcases have been issued for records, cassettes, 8-track tapes, film, video cassettes, compact discs, DVDs and even toys instead of or in addition to the more common jewel cases or keep case, and may be chosen for aesthetic or economic reasons. Larger slipcases that are designed to house one or more items are often used in packaging for special edition releases or box sets.

The Writers' Prize, previously known as the Rathbones Folio Prize, the Folio Prize and The Literature Prize, is a literary award that was sponsored by the London-based publisher The Folio Society for its first two years, 2014–2015. Starting in 2017, the sponsor was Rathbone Investment Management. At the 2023 award ceremony, it was announced that the prize was looking for new sponsorship as Rathbones would be ending their support. In November 2023, having failed to secure a replacement sponsor, the award's governing body announced its rebrand as The Writers' Prize. The Folio Academy is the international group of writers and critics who nominate titles for the award.
