* On third-party libraries: SLIB and Snow Fort provide portable third-party SRFI implementations for R5RS and R7RS Scheme respectively.
chez-srfi is included as the de facto SRFI implementation library for Chez Scheme, IronScheme and Loko Scheme with broad R6RS compatibility.
CHICKEN Scheme provides third-party SRFI libraries through its package manager, in the form of eggs.

** Disclaimer: The responsibility for stating that a SRFI is supported is on the Scheme implementation developers.
