How are you people getting the Shorter OED on your Kobos? I've got the Chambers 1908 on there using the instructions on the thread below.
I have tried multiple times to add the SOED as well, to no avail.
"To use the new dictionaries:
Connect your Kobo to your PC.
On the Kobo go to the ".kobo\dict" folder, and rename "dicthtml.zip" to "dicthtml.backup.zip". This backs up your existing English dictionary (which I assume you already have installed).
Download the appropriate zip file below and unzip it to extract the dicthtml.zip file inside. Do not unzip the dicthtml.zip file.
Copy the dicthtml.zip file to the ".kobo\dict" folder on the reader.
Eject/disconnect your Kobo.
Go into the dictionary screen, e.g., if you have a book open, tap the book icon on the bottom menu, and select Definition.
Flip the language from English to e.g., Deutsch and back again. This makes the Kobo refresh the English dictionary cache. You only have to do this once.
The new dictionary is now ready to use."
