The numbers are listed in RFC-960, "Assigned Numbers".  This is availabe
for FTP from SRI-NIC.  Get the file "RFC:RFC960.TXT".  A couple of times
a year, a new version of "Assigned Numbers" is published, with a new
RFC number.  RFC-960 was published in December 1985.

I've removed a few blank lines in the two pages below.

IEEE 802 SAP Numbers


                    IEEE 802 SAP NUMBERS OF INTEREST

   Some of the networks of all classes are IEEE 802 Networks.  These
   systems may use a Service Access Point field in much the same way the
   ARPANET uses the "link" field.  For further information and SAP
   number assignments, please contact: Mr. Maris Graube, Chairman, IEEE
   802, Route 1, 244 H, Forest Grove, Oregon, 97116.

   The IEEE 802.3 header does not have a type field to indicate what
   protocol is used at the next level.  As a work around for this
   problem, one can put the Ethernet type field value in the IEEE 802.3
   header's length field and use the following test to determine the
   appropriate processing on receipt.

   If the value in the length field of the IEEE 802.3 header is greater
   than the Ethernet maximum packet length, then interpret the value as
   an Ethernet type field.  Otherwise, interpret the packet as an IEEE
   802.3 packet.

   The proposed standard for transmission of IP datagrams over IEEE
   802.3 networks is specified in RFC 948 [127].

Ethernet Numbers


                      ETHERNET NUMBERS OF INTEREST

   Many of the networks of all classes are Ethernets (10Mb) or
   Experimental Ethernets (3Mb).  These systems use a message "type"
   field in much the same way the ARPANET uses the "link" field.

   If you need an Ethernet number, contact the XEROX Corporation, Office
   Products Division, Network Systems Administration Office, 333 Coyote
   Hill Road, Palo Alto, California, 94304.

   respectively.
