What Casemate, Llc does

Casemate, LLC, operating as Casemate Group, is an independent, family-owned book publishing and distribution company founded in 2001 and headquartered in Havertown, Pennsylvania, with approximately 30 staff across US and UK operations. The company operates two integrated business lines. The publishing arm comprises four specialist imprints: Casemate Publishers (military history, aviation, and naval history, producing up to 90 new titles per year), Oxbow Books (academic archaeology and ancient history with a 40-year backlist), Brookline Books (Greater Delaware Valley regional history, launched 2023), and Windgather Press (landscape history). The distribution arm provides sales, marketing, warehousing, fulfillment, and digital distribution services to over 100 client publishers in North America through divisions branded Casemate IPM (trade), Casemate Academic (scholarly), Casemate Digital (eBooks), and Celtic Books (Celtic-interest titles).

Casemate's distribution infrastructure relies on industry-standard publishing technology rather than proprietary platforms: ONIX metadata management, OCR scanning for backlist digitization, multi-format eBook conversion (reflowable and fixed-layout ePubs, web-optimized ePDFs), integrated warehousing and fulfillment systems operated through partner Books International in the US and Pen & Sword Books in the UK, and a client portal for account management. Global reach outside the Americas is delivered through Script Publisher Services (formerly Casemate UK, rebranded January 2025), a joint venture with UK-based Pen & Sword Group representing approximately 180 publishers. The company's go-to-market combines direct in-house account management for major retailers, independent sales representatives for regional/niche coverage, attendance at trade shows (Frankfurt Book Fair, Society for Military History, ALA), and direct email sales campaigns leveraging curated catalogs.

Revenue is generated through two streams: book sales across proprietary imprints (trade, academic, and special-interest retail/wholesale/library channels) and fee-based distribution service agreements with client publishers seeking North American or global market access. Pricing is bespoke per client and not publicly disclosed. Casemate serves trade publishers, academic and professional publishers, specialist/niche publishers (military history, archaeology, Celtic studies), and the library market across North America, the UK, and global English-language markets. The company remains privately held with no external institutional investment, no public listing, and no disclosed financial statements.
