Most remote systems require a private or public login name, and a
public or private `password.' The systems that contained databases of
searchable bibliographic information had similar fields in their
records, such as `author,' `title,' and `subject,' (or `descriptor' in
Dialog). This information was probably stored in a common format--the
MARC record format or a variation of it. The systems I entered all
allowed their information to be carefully searched using Boolean
logic. Finally, all of these systems featured a character-based
interface with the option to enter commands directly (over-riding any
menus).
