hetalia | Anyone also interested in artbook/anthology?

Hi, I've been into Hetalia for more about 3 years now, but only started buying things from the fandom half a year ago when I finally had my Paypal account. That means I've missed a lot of good stuff going on around, and it really disappoints me. I hope I won't miss all the actions again, so there's a few things I want to know.
I'm really interested in artbook and English anthology, because I do not know Japanese, and I love artbooks, I'm very eager to find stuff that I can understand. There's been a few English anthology around, like the Bromance, and the 1920, and the Ultimate Nations. Finding them is really hard work, but when I finally arrive at their LJ community, all of them have been closed for a long time. Then again, I have no clues how to look for the anthologies in the first place, I mostly come across the mentioned ones while looking for something else. So, in order not to miss any of them in the future, I wonder if anyone knows of a site frequently updating the status of English anthologies available? Most of the projects have their own DA and LJ address, I just don't know how to keep track of them.
Thank you for all your help.
