Matilda reads so many books. This library is - she sits down and estimates it - fifty times the size of the town library in Lyndonville. Finishing a whole section here would take years.

It is sometimes hard to tell whether a thing is fictional or not. She writes down lists of such things to look up.

Talking cats do not exist. Vampires do. Fictitious plant-related magical abilities do not exist. Aleism does (Matilda is, privately, skeptical about Sennah).

Do shrens exist?
