Unfortunately the vast majority of dictionary files are in "stardict" format and the conversion to "dict" has yielded mixed results. I was hoping to host _every_ dictionary, good and bad, but will walk that back now. A free VPS could at least run the OED.
Was the plan to do this in a legal fashion? If so, how?
As an alumnus I could do this by showing up in person to my university and accessing that way. But I'm not going to.
Edit to add: Also, "i scanned the first edition decades ago" sounds like quite a story. 13 volumes? What project were you doing?
And it's already in 'dict' format so I didn't need to convert.
That takes HTML files as input, and I don't know where those are found. ISOs of CD-ROM editions from 1996 and 2009 are online, but it looks like an adventure to install the software and/or extract the data.
The trouble with piracy is that provenance is so shaky, with plenty of chance for bugs or alterations...
