Learn English – Word meaning “feather-like”

There is the word bookish:

fond of reading; studious

and bookishness for the fondness of reading:

the quality or condition of being bookish

The word has other connotations as well but I think this word is the closest single word you can get for this meaning.

As I mentioned in the comments, lectiophilia would be a suitable neologism for the love of reading if we follow the path of bibliophilia (and such words suffixed with -philia). Lectio means reading in Latin. In the end, it can always be used as a nonce word.

I think you may say:

nobody yet has put a final word on it.

suggesting that developments are still underway and a lot of research has probably to be done before a final answer is found.
