NORTH AMERICAN MILLERS' ASSOCIATION - NAMA
https://namamillers.org/about-nama/  ~  Member companies operate 150+ mills across 30+ states, Puerto Rico, and Canada.  Check out the "Members" link to learn of 37 milling companies in the U.S. which is not a complete list of those who provide flour & grains for us, but it's a good beginning for researching & learning.  Also, we can't equate names of mills w/name brands of baking flour, as so many "corps" own various, & sometimes many, name brands.

The NAMA history is rooted in THE MILLERS' NATIONAL FEDERATION OF THE U.S.A.  Read the HISTORY link:

On the "atlas obscura" website, there is a story about Barbara Ketcham Wheaton & that it took her over 50 years to compile a database of around 8,000 items, mostly cookbooks. It's called THE SIFTER (thesifter.org).  I have a hard time navigating in this database website, & maybe it's just me not having the necessary computer skills!  https://www.atlasobscura.com/articles/how-to-find-historic-cookbooks  --  On this "atlas obscura" website there are a LOT of additional items which are noted in other RESOURCE sections, such as Museums, etc.

UNIVERSITY-LIBRARY WEBSITES:

Many universities have "Special Collections" Libraries/Archives. If they allow in-person viewing, usually by appointment, from my experience, you select from the digital database - you can't eyeball the archives in person. Also, you may need to have an "approved" reason to see these items. The requested books (usually a limit) are brought out; you wear cotton gloves which they give you, along with a pencil & pad of paper. You can't have your purse, etc. with you in the room. There are lockers to store personal items. The following are some of the libraries with cookbook collections for the possibility of visiting, & you'd call to find out the requirements.

The Atlas Obscura website lists 4 cookbook collections in libraries:

1) wine at UC-Davis, CA;
2) San Antonio Mexican Cookbook Collection at the Univ. of TX; N. America's largest known Mexican Ckbk. Coll.

 AIB – American Institute of Baking International - Manhattan, Kansas -- This baking school is thriving, but online in articles you will read that the AIB has a museum, but IT NO LONGER EXISTS!  AIB began in 1919 in Chicago (a history point I remember from being there).  An article online today said the museum began in 2012, but I was there 10 years before & was in the one-room museum for around half-a-day.

Besides the more focused collections at the museums & university archives, there are also small-to-large acreages of "open air museums" throughout the U.S. (& other countries) which have sections of artifacts or entire buildings devoted to the historical preservation of the house (baking) and farm buildings (ag-related equipment) & the other related historical artifacts.

Shelburne Museum - Vermont  (a living history museum) -  On their website they mention a collection of "food molds."  I believe they are referring to their carved wooden cookie molds used for springerle (if they're the small ones in the 2" - 3" range, sq., rect., round); for spekulatius or speculaas (if they're in the 4"x7" range); & if there are larger ones, for whatever are called molded ginger cakes. I have not seen the collection - don't know how many or the quantity they'd put out for viewing if they do have an exhibit, etc. But just to know for further inquiry for a visit. Their website slideshow in the Dutton House has a photo of a cooking fireplace & a kitchen.

***Throughout the country, most counties have a Historical Society Museum.  Some of them will have a few items, to a full kitchen or a cupboard/pantry area of shelves on which are displayed "kitchenalia" - kitchen artifacts.  But there's usually no story/history given about them & most guides have no knowledge of names & how used!  Also, there are State Historical Societies.  Check yours to see if they do exhibits regarding home baking/food/grains, etc.

PODCASTS:

Podcast: Gold Medal Flour ~ He begins at 8:40.  (Prior to that he talks about going into the abandoned bldg. & painting graffiti all over inside!  But at 8:40 he begins about the part of the mill being converted into the Mill City Museum, which has a lot about Pillsbury besides General Mills' products.)

7a) - PROFESSIONAL - DEGREES - Throughout the U.S. there are dozens of Pastry & Baking schools within Culinary Institutes. Use a Search Engine to scan through what you might be looking for.  Also, type in Culinary Institute Pastry & Baking schools in (enter a state).  Also, Culinary Arts or Baking & Pastry Arts.

A baking school of particular note is the AMERICAN INSTITUTE OF BAKING - INTERNATIONAL (AIB).  It began in Chicago in 1919, & in 1977, moved to Manhattan, KS.  In 2018-19, the school realigned it's focus to change with the changing times of the baking industry & what people wanted to learn.
The AIB is where the Baking Hall of Fame began in 2006, & today the framed photos of those who've been honored through the years are at Bundy Baking Solutions's Corporate Headquarters in Ohio.  (P.S.  No matter what you read online, there is NO AIB museum today!  All the artifacts went to Bundy's.)
