The top left layout has too much space between the top grouping (which works) and the bottom groupÉÉcloseness works here!
Bottom left works well as a unit. The placing of the author at the top is a good idea and works. The amount of space between the groupings is good. IÕd suggest not using centered layout for last group.

The top and bottom right are nice experiments that are beginning to work. Grouping of the title and tucking in the smaller words (the and of) creates a nice overall shape and is easy to read. The bottom right works best.
Nice job!
