This file collects a chronology (and perhaps a few unrelated facts) of
several inter-related series of books by Isaac Asimov.  The portion
starting on the next page is designed to be machine readable, but human
comprehensible since initially data entry/editing will be done with GNU-Emacs.

This is the key for the layout:

Blank lines and comment lines starting with ";" are ignored.

There are 3 fields (delimeted by vertical bar ["|"]):
1) Date: As detailed as can be determined.  Any portion of the date
	that is not exactly determined is followed with a twiddle
	("~") and the max error.  The date may be a span, indicated by
	two dates seperated by a dash.  The date is identified by
	leading characters as belonging to one of the following
	chronologies described here.  The date may also represent a
	correlation by being followed by an equal sign and another
	date in a different format.
    Christian era of Old Earth given as: ADyyyy/mm/dd:hh:mm:ss with
	all fields after the year optional and indicated by the
	presence of the preceding delimeter.
    Galactic Era given as : GEyyyyy
    Era of the First Foundation given as: FEyyy with additional fields as I
	figure out how they record portions of a year.  In the book "Second
	Foundation", page 73, there are two references which give three
	numbers seperated by commas, either month, day, year or day, month,
	year.  It's not clear from the context.  Somewhere earlier in this
	book I seem to recall a date being given as one of these two (without
	year?) with explicit month and day, but don't remember which.
2) Reference: An indication as to which book in my collection and
	where in that book the information for the entry was found.
	They are given in a form of BOOK:pages where BOOK will
	eventually be a reference to my on-line bibliography but for
	now is probably the title.
3) Textual description of event (may be continued with indented lines)

;;;; The original robot novels

; The determination of all of these dates are inter-related:
; The century is guestimated (with given uncertainty) from comments in "The
;	Caves of Steel" pp 17-19, the lower part of the year is based on Op.
;	Cit. pp 32-37 which mentions party in '02, and related times given as
;	rough deltas.  The individual digits of the uncertainty indicate the
;	uncertainty in that digit position, thus AD4721~1902 means that the
;	century is between 30 and 59 and the year within century is between 19
;	and 23.  The Naked Sun takes place a few months after Caves of Steel,
;	so the date is given as the next year to sort right but the
;	uncertainty is increased to include possibility of being in the same
;	year.
; | The Robots of Dawn:43-44 | Aurora was first extra-solar planet settled.
;	Originally called New Earth, the name was quickly changed by the
;	settlers.

; The following entry, although very specific in the location it occurs,
; disagrees with several other pieces of explicit data.  Most notable is that
; this is some thirty days after the preceding entry which comes from the
; same book.  It also contradicts the relationship between FE and GE given in
; Foundation, page 7.  Furthermore the section represents the further details
; of dates differently than elsewhere.  The specific entry contains many
; other tidbits of date data, but due to suspect nature and low utility they
; are not included here.
GE11692=FE348	| Second Foundation:144	| Start of Stettinian War
FE443	| 2nd F:73	| Death of Arcadia Darell (Actual date 1, 7, 443 F.E.)
