Amidon has a good catalog, but you'll only see the products they chose to list. Their ferrites are primarily Fair-Rite or Magnetics Inc., while their powdered irons are from Micrometals.
Adams, Elna and most others *don't* have an online catalog, at least not in the way we're familiar with, like Digikey and them do. You'll have to go back and forth a few times between manufacturer's product listing, checking that they even make the kind of thing you're looking for (shape, material, A_e, gap, etc.), then checking if that part is carried and in stock.
The largest manufacturers carried by these companies are usually among: Fair-Rite EPCOS/TDK Ferroxcube Magnetics Inc. (ferrite, powdered iron, stripwound) Micrometals (powdered iron) VAC and HMG (amorphous/nanocrystalline)
