Always wondered about this, for when you are picking up books from places to post on here?

Under Community and Top 50s you can see the top 50 WL books for the club. 

I personally stick to genres I know and after awhile you learn who not to buy because they are heavily posted (Nora Roberts, James Patterson) and who moves really quickly (Jim Butcher, Shannon McKenna, Charlaine Harris). 

I just periodically do WL searches of my favorite genres and see which authors are pretty much all WL.  If I'm going to the big FOL sale then I will search the Top 50 WL and make a list of some books to take with me and keep my eye out for.

I've found that erotica, Urban Fantasy and paranormals go really well.  Newer celebrity cookbooks (like Foodnetwork books) go really well but it's hard to find them really cheap and they are more expensive to mail.  Newer crafting books go really well but again they are more expensive to mail.

You can check out individual wish lists by clicking on any member's username. It's usually lit up in blue. Then , in the upper right area, you will see the links for his/her bookshelf and wish list.

It is also interesting to see how many books a member has sent or rscieved. But as the default is "Do not show" you can not always tell. It is up to each member to go to the setup page and UNcheck that box.
