Time Charts

Future histories generate time charts, most famously Heinlein's. Poul Anderson modelled his Psychotechnic History time chart on Heinlein's. Later, Sandra Miesel compiled the Chronology for Anderson's Technic History. There are similar time charts for:

James Blish's Cities In Flight;

Cordwainer Smith's Instrumentality Of Mankind;

Larry Niven's Known Space;

Jerry Pournelle's CoDominium. 

Blish's Haertel Scholium generates branching timelines. Thus:
