Is there a centralized directory or database of local historical societies or organizations for the United States which shows the information and services they provide in a consistent format for each society?
I did look at the Local Historical Society Genealogy question which to a degree spurred this question about resources utilized and available to them.
I know internet search engines like Google/Bing/Yahoo/etc exist -- but finding out their location and hours of operation requires individually searching for each society, knowing the exact names, etc. -- and their region / period of coverage is not always apparent.
Even though technically several of these are libraries they commonly also do not show up in searches on WorldCat as a library nor their holdings.
I also know Cyndi's List has a list of societies, but it is just that -- a list of societies and a link to their websites, not a searchable index with areas of coverage, nor services they provide.
All of the societies are using different tools and website formats, so trying to navigate their websites to figure out what services they provide and how to initiate requests for services can be pretty frustrating sometimes.
Key Data Points I am looking for, the areas of coverage in particular being searchable.
- Name of the Society / Historical Library
- Geographic Areas of Coverage
- Years of Coverage
- Website
- Contact Information
- Phone Number
- Mailing Address
- Collection Holding, especially Unique Ones
- Publications
- Research Fees
- Cost of Membership / Membership Benefits
Question: Is there a centralized Historical Society index / database for the United States that contains this type of information?
