Steam and other Valve products distributed via Steam use certain third party materials that require notifications about their license terms. You can find a list of these notifications in the file called ThirdPartyLegalNotices.doc (Microsoft Word or 3rd-party Office application required) or ThirdPartyLegalNotices.txt distributed with the Steam client and the Source 1 & Source 2 engine games. Where license terms require Valve to make source code available for redistribution, the code may be found here.
