I apologize. I know it is confusing, and I am sorry.
Libronix is a brand name owned by Logos. The Libronix Digital Library System is what we call our software platform. Logos Bible Software is what we call the products that contain both the Libronix DLS and a collection of electronic books, because without the books there is nothing Bible-specific about the Libronix DLS.
Other companies use the Libronix DLS, too, under license from us, and they give their products (consisting of the Libronix DLS and their electronic books) different names, like eBible or The Essential IVP Reference Collection.
We created the Libronix brand many years ago with the idea of separating our technology from our content-based products in order to make it easier for other companies to license and use our technology in their own products. We did not use the word “Logos” in the technology brand in order to avoid confusion between ours and other Bible software packages; we also had secular publishers licensing the technology, and the word “Logos” did not mean anything in that context.
Back then we also imagined that we might split the company into two organizations, one focused on technology and one on Bible software content. We created the Libronix Corporation as a wholly-owned subsidiary of Logos in anticipation of that split. Our strategy has changed, though, and we are now completely focused on serving the Bible software market and our publishing partners in Bible-related publishing. Libronix Corporation still exists, but as no more than a file folder of paperwork and a separate phone number that rings at the Logos reception desk.
What do we call our product? Logos Bible Software. This is the product you can buy, in specifically named collections: Logos Bible Software Pastor’s Library, Logos Bible Software Scholar’s Library, etc.
What do we call our software platform? The Libronix DLS. This is the technology platform shared by many publishers, including Logos Bible Software. When you are installing or activating or upgrading the software itself you are working with the Libronix DLS, and all of those actions affect all the Libronix DLS based books you have installed, regardless of which product they came in.
And finally, Libronix is a word that we made up. That made it easier for trademark and domain name purposes. We pronounce it like “library” and “electronics”.
