| FWIW I went looking on archive.org and found "ERIC ED378962:
| Developing CD-ROMs: Pitfalls and Detours on the Road to the
| Digital Village." which had a very brief mention of High Sierra:

|
| There are also a number of High Sierra format CDROMs on the
| archive.

|
| Includes a table of the details.
|
| Also adds:
|
| "Note: High Sierra and ISO 9660 formats differ slightly:
|
| - Two fields changed position.
|
| - All date and time fields have an extra byte In ISO 9660 to
| describe the 15-minute offset from GMT."

| This "CD-ROM Professional 1990: Vol 3"[0] (https://archive.or

|
| * "At the slow pace with which NISO was proceeding (in nine
| months it still had not even named a committee), and with the
| historical knowledge that standards organizations take from
| three to five years to develop a standard, a meeting between
| Xebec and Reference Technology was held in August of 1985. At
| this time it was agreed to approach other participants in the
| industry to see if there was interest in convening an
| industry group to expedite the formation of a logical format
| standard. In October of 1985 representatives from the major
| CD-ROM industry participants met at the High Sierra Hotel in
| Lake Tahoe and agreed to cooperate in formulating a logical
| format standard.
|
| From this meeting the ad hoc group was formed and became
| known as the High Sierra Group. John Einberger of Reference
| Technology was selected as chairperson.
|
| From December 1985 through April 1986 this group met five
| times and completed a final draft proposal in May 1986. In
| June 1986, this proposal was presented to NISO and the
| European Computer Manufacturers Association (ECMA). In
| January 1987, the approval activity was passed on to the
| International Standards Organization (ISO) which performed
| its final edit in October 1987."
|
| * Article: "HIGH SIERRA VS. ISO 9660: A SUMMARY"
|
| * "NISO's first foray into CD-ROM is Z39.60, a standard for
| the volume and file structure of CD-ROM (and, potentially,
| other optical media). This standard is much better known as
| the High Sierra Group standard."
