I'm looking for NLP datasets/corpora with small vocabulary sizes -- less than 5K unique words, but smaller still is better. I've tried looking for e.g. datasets of children's books but I've not found anything that has a decent length of corpus while also having a small vocabulary size (e.g. any children's book with very small vocabulary sizes also tends to be very short!) If anyone can share anything fitting this description I'd be really interested to hear.

    $\begingroup$ Welcome to DataScienceSE. Afaik it's a bit unavoidable that the size of corpus is proportional to its vocabulary size. Maybe there are resources for people who learn English as a foreign language, or essays by students? $\endgroup$
