EMMA (Electronic Municipal Markets Access), The Official Source for Municipal Disclosures and Market Data, is a one-stop website sponsored by the MSRB (Municipal Securities Rulemaking Board), offering a "comprehensive source for official statements, continuing disclosure documents, advance refunding documents, and real-time trade price information on municipal securities." An Education Center explaining both basic and more advanced concepts of bond investments, and links to governmental and non-governmental information resources regarding bond investing make the site particularly useful.
