HH Series List Wanted

One of my friends from PBS is an avid reader of Harlequin Historicals and I am attempting to compile a completed list of the series from book #1 to the current books being published. I have searched all over the internet for such a list an have been unable to locate one, despite the fact that others seem to be seeking the same thing. Also, I have discovered that there are actually two sets of Harlequin Historical series - the original (HH), and Harlequin Historical Subscription. (HHS) Therefore, I am going to attempt to compile lists here in hopes that others who are searching will be able to find it, or can leave comments contributing to it.

Thanks!
