When i was playing this game, i found out,
The [school] need book to unlock the [Animal husbandry],
The book need paper and leather to produce.
The leather need [Livestock] to produce.

you make leather with a Pasture. Paper makes research, book makes more research... Paper is all you need....

You can just use paper for research until you can make books. In fact i researched most of the way through mana before realising there was a book lol.

When i send the paper to the school, The worker cannot do it, they stop at the Sawmill. I already select the agriculture as reach.

Research also uses money and sometimes other resources besides the paper/books.
