Once the unlatching process has been started, you can upload the PDF file (and EPUB where available) or ZIP (for chapter files) for titles with the status "to be unlatched". You can do so by clicking on the individual titles in the collection and navigate to the Files tab. Please note that the files must not exceed 50MB and the e-books should include the cover page and no crop marks.
Please then review the metadata entered and make any necessary updates. This data will be used for creating the MARC records and cannot be changed after you select "Submit for Unlatching".
Once you have changed the status for that title to "Submit for Unlatching" we will review the file(s) and forward them to our hosting partners if everything is in order. The title will then be available on the OAPEN platform the next working day, and you will receive an automatic email notifying you that the title(s) has (have) been unlatched.
