Books & documents

eBook and document DRM, from upload to authorised device

A centralised repository of your EPUB and PDF/A files, and the fulfilment system that turns a sale on your site into an encrypted, licensed download on your customer's reader.

What the reserve does

Digital Media Reserve is a web-based service built by DMI around the current edition of Adobe Content Server — version 6.5, now continued as ByteBooks Content Server. It holds your files, issues the licences, and hands your retail channel a download link it can trust.

The encryption is bound to the reader's authorised identity rather than to the device alone, which is why a book bought on a phone appears on the laptop and the e-ink reader without anyone re-buying anything.

In the reserve

Centralised repository
Every edition of every title, held once, versioned, and never re-uploaded per retailer.
Fulfilment system
Licence issue, download link generation, re-issue and expiry, all logged against a transaction ID.
Retained inventory
We keep the file available for customers who already bought it, even after you withdraw the title from sale.
Downloads report
Review every fulfilment online — by title, format, retailer and period.

Capabilities

What you can do with a protected title

Sell it outright
A perpetual licence to the buyer, readable on every device they authorise.
Lend it for a fixed term
Make the book available for a set number of days; permissions expire and the content returns itself, with no action from the borrower.
Licence it to an institution
Concurrent-user or seat-based access for a school, university or corporate library.
Raise protection on selected titles
Resource-level DRM lets you enforce stronger rights on the titles that need it, rather than on the whole list. Requires RMSDK 10.0 or above in the reading application.
Choose the rendering engine
Serve an EPUB through the EPUB 2 or the EPUB 3 renderer, so older reading systems keep working while new ones get reflowable, accessible layout.
Re-issue without re-selling
A lost file or a new device is a regenerate call, not a refund conversation.

Content policy

Publishers using the reserve are the content providers, and remain responsible for complying with the local, national and international law that governs their titles. We do not screen catalogues, but a small set of material is not accepted — and submitting it in the file, the cover image or the metadata ends the account.

Ask for the full policy
Not accepted
Pornography; libellous material; anything the publisher does not hold the copyright or the right to distribute.
Public domain
Accepted, but we may ask you to validate that a given title genuinely qualifies.
Advertising
Material inside the eBook whose main purpose is selling something other than the eBook itself.
Metadata
Title data is covered by the same policy as the file it describes.
