For safety reasons, BGMI has implemented stringent policies regarding access to these caverns.
For this reason, in 1997 BGMI entered into a specimen-recovery agreement with Geoprime Minerals Company (Casey and Jane Jones).
I deeply appreciate and respect the perspectives, discussions, and insights I have gained from interaction with numerous BGMI personnel.
The minimum configuration to run die single user version of BGMI is a personal computer with: IBM XT, AT, PS/2, or compatible (80286 or faster processor recommended); MS-DOS or PC-DOS 3.1 or higher; MS-DOS CD-ROM Extensions (MSCDEX) version 2.0 or higher; 640K bytes of RAM; 1 megabyte of free space; monochrome, CGA, EGA, or VGA monitor; ISO 9660-compatible CD-ROM drive with cables and interface card; and parallel or serial printer port for printing.
The software that runs BGMI should be installed on a hard disk with at least one megabyte of available space.
The user can enter a customized message (up to 70 characters) to select the default message, "Available in this library." Since BGMI covers over 675 source publications in more than 2,000 volumes and editions, tagging all titles is a time-consuming process.
Two methods are available for searching BGMI - A menu driven search by name or an extended search option that allows searching for names including titles, prefixes, and suffixes), birth and death years, title of a source publication, and sources with portraits of the person.
This is an important time-saving feature, for as noted above, names appear in BGMI exactly as they are listed in the source books.
