In addition to the link to Scribd romance books, I made a link with searching for macmillan and then sorting to books and the genre romance on the left. Seem to get more titles this way I can see. Only 185 show as listed. Assuming the search only pulled up macmilan published stuff and not titles with that name in it. I see some nice historical romances with this search.

eta: unfortunately, it seems to be pulling up harlequin and kensington titls also once I page a few pages. The first 2 pages seem to be MacMillan. Don't think there is a lot of romance in the 1000 offerings.
I wish there was a way to search properly by publisher and then by their designated genres and subgenres. Searching for the terms always brings way to many unrelated things.
eta: I think I got it. I put in macmillan publishers and put it in quotes. Get 96 results and they seem to all be by the publisher.

I think I remember searching for harlequin lines that way, putting it in quotes like "carina press" etc.
