Status of deployment in different parts of the world

This section takes a geographical approach and shows interactions between these organizations. A third section will focus on LCP technology providers.

France has been the first country to move ahead with LCP, especially for e-lending, which explains why a large set of LCP compliant servers and applications are on the market today.

e-lending: the national e-lending service called PNB (Prêt Numérique en Bibliothèque) provides ebooks to a large set of French public libraries and distributes both LCP and Adobe protected ebooks, provided by different distributors (Numilog, Eden Livres, Immatériel, Vivlio …). PNB explicitly recommends the use of LCP for EPUB and PDF titles and has developed a Readium based mobile application (Baobab Reader) with automatic synchronization of borrowed ebooks to push its usage. 

Two other e-lending solutions are LCP compliant: La Médi@thèque numérique and BiblioAccess.

RetailePagine (which also powers Place des Libraires, Bookeen, Gibert, Gallimard and others) provides its complete catalog of ebooks as LCP and Adobe protected content (when it is not simply watermarked), and its comics are only LCP protected.

Numilog has also deployed LCP on its library website, on GirlyBoox and on its white label network. This involves a catalog of 500.000 EPUB and PDF ebooks, in French and English (press release).

Some publishers, like Editis, have started selling their production with an LCP protection on their website. 

Academic publishing: John Libbey Eurotext has adopted LCP for its academic publications in 2022.
