Most of the books I've read were hardcover without jackets.
When I belonged to the Science Fiction Book Club I bought books based on authors mainly.
When I converted to electronic format I reaquired the works I liked best and supplemented with more from the same author.
Many of the short stories I like have no cover art.
Recently I've been grabbing audio books. On youtube the cover art sometimes shows on the video but I don't 'watch the video' I listen to it.

authors and by series.
. I like sci fi /war fare/ vengeance.
some series I have read
mack bolan is kinda like the punisher.
battle tech, loosely based on the robotech lay out based after the fall of the star league.
hammers slammer, futuristic mercenaries, hired as military support. when a planetary government, needs things settled fast.
BOLO's
self aware (or semi self aware, depending on what part of their history the story takes place in) super tanks.
jungle tracks: semi fiction, based on viet nam era tank war fare.
I need books that have a lot of action, to hold my attention. long drawn out dialog puts me to sleep.
star wars books on tape are great for that. ;-) LOL
