Adding content to listal

Sorry I must be a super n00b but there are lots of comics and books I can't find on listal and I wanted to add them to listal, is there someway I can do that?

Go here: www.listal.com/search/books/ and do your search
When nothing is found you can add an item to the database using the ISBN or the amazon ASIN (the ASIN is in the URL, see example below)... If you are having trouble finding nothing just put in some random text (thats how I do it "fsdfdsfgadsfas") There is probably another way, but thats what I do.
www.amazon.com/Hunger-Games-Suzanne-Collins/dp/0439023521/ref=sr_1_1?ie=UTF8&qid=1302483410&sr=8-1
In this case it would be 0439023521
