Foundation Directory

The biggest single directory as far as I know of grants and grant-making organizations (at least in US but maybe also globally), categorized many different ways. Available at many/most? public libraries. Locally including at least Eugene Public Library, ...? Eugene library has also offered free training (eg June 13, 2019) on using the directory.

The Foundation Center offers other resources to foundations and grantees as well.

I don't know any people there, but if we all tapped our nonprofit networks I'll bet we could find someone close to them.
