The collection of Time Patrol stories published in The Magazine Of Fantasy And Science Fiction grew from four to five stories and lengthened its title from Guardians Of Time to TheGuardians Of Time whereas the later collection of all published Time Patrol stories grew from seven to nine to ten stories and shortened its title from Annals Of The Time Patrol to The Time Patrol to Time Patrol.
Annals Of The Time Patrol amalgamated The Guardians OfTime and Time Patrolman;
The Time Patrol amalgamated Annals... and The Year Of The Ransom and also included the new "Star Of The Sea";
Time Patrol added "Death And The Knight."
Thus, everything is now in one volume except the long novel, TheShield Of Time.
