I just wanted to share this link. It is an open source library of very old books and other publications including seed catalogs, books about apples and cider making, fruit growing, and all kinds of publications from the USDA from many years ago.
I consult it and Hathi Trust quite often.
I believe they obtained the articles from the U.S. National Agricultural Library:
Here’s a favorite source from 1915. It is a master’s thesis from the Oregon Agricultural College by Harriet Barbara Gardner. It has just about everything. Descriptions of apple varieties, and when they are in their prime. Recipes and ratings for different kinds of cooking and baking.
