We talk a fair bit! Gutenberg is the source for 95%+ of our productions, and personally I upstream any transcription issues I find.
What differs though is the mission. Gutenberg generally wants accurate digital translations of the original source texts, whereas Standard Ebooks tries to balance that out with better readability. Both are valid approaches, and there’s space for both of us.
Just curious... do you ever reach a consensus on a text that you decide to share between you?
Can you actually share the full .EPUB file, or do they object to the expanded size with bundled fonts and formatting, resulting in identical HTML but otherwise different content in the ZIP?
It hasn’t happened before but never say never. What we do do though sometimes is contribute our own transcriptions to Gutenberg first, then use that as a base for the Standard Ebooks version.
Are these two organizations otherwise not on friendly terms, and able to exchange ebooks?
