Production of Accessible EPUB is a multi-stage process. The first stage, which leads to the delivery of an Intermediate file, is carried out for all books submitted to desLibris, whether  submitted for licensed distribution or conversion. There is no charge for Intermediate files.

Every publisher partner has a dashboard on which modules for file delivery and titles , 

ONIX records for most titles from Canadian publishers are available on Biblioshare. If publisher Onix is not supplied with the file, , the Biblioshare ONIX is copied and used as the basis for the enhancements described in the ONIX section of the Best Practices page. 

The first stage ends with the production of an Enhanced or Intermediate EPUB3, which is suitable for distribution, but lacks the Alt-Text content which is required to meet standards.  This file is identified in the Repository. 

After creation, Intermediates are stored in the Publisher Repository. To complete the production of an AEPUB meeting best practices standards, the publisher must select the file and place a "conversion order." 

Accompanying the Intermediate file is a spreadsheet generated as a byproduct of the conversion process. This provides a template for publishers or authors to provide the necessary descriptions. Alt-text creation may alternatively be contracted to desLibris. The file may be exchanged several times between publisher and production team before signoff.  

The end result of the process is a file which meets the standards shown on the Best Practices page. After payment, this file, the property of the publisher, may be delivered to distributors and licensed for distribution through desLibris.

All Finished files are also stored on the Publisher Repository, from which they may be downloaded or delivered directly to distribution partners.
