Space once after the issue number and open parenthesis. The year of the issue comes next followed by a colon. Close the parenthesis to finish this section. Without spacing after the months, put your initials in parenthesis. If someone elses initials are already there, just erase their's and type yours.
Initials tell who checked-in the latest issue.
This just tells the date this line was last updated. You don't need to do anything here.
