SNOMED CT (R) Permanent Package Releases
The files listed below were previously included in the SNOMED CT International Edition Release Format 1 (RF1) distribution. Because the files do not change from one release to the next, as of January 2015, the files have been made permanently available to IHTSDO Member National Release Centers and Affiliate Licensees via Internet download.
