Each file must contain at least 2000 words.
The sum total word count for all files within one single source cannot surpass 100,000 words.
Multiple files may be uploaded as long as they stay within these limits cumulatively.
What happens if I go over these limits?
For sources created in the Sources Dashboard: If you exceed the total word count, you will not be able to save this particular source. Remove some of the files until it fits under limit again. During book creation: If your entire text exceeds any one of these restrictions during its processing stage, then it won't move forward onto next step in process.
