I'll have a go, sure I'll get pulled up if off.

read 4, write 2, execute 1  add these together for permissions
owner, group, anybody

I never did anything on a PC with other people having access so I never 
made a file only executable by anybody but I don't see why not.
As you wrote reading_room.tcl presume that belongs to you.
I don't know anything about tcl as yet but assume it's executable as it 
is and does something.
You may have a group librarians that want to have read/write access to 
reading_room.tcl
Assume you have backups of the files.
guess books.db wants to be 644
"su -"
"chmod 644 books.db"
  or if the librarians want write access to it.
"chown you.librarians books.db"
"chmod 664 books.db"

"chown you.librarians reading_room.tcl"
"chmod 771 reading_room.tcl"
