Richard - The short answer is "yes", but reality makes us go the long way around. Under the
Publishers tab, if you click on "Search" you get a full 192 List, where one of the columns marks
Pubs not accepting queries at this time with a red circle/slash badge. Of course you knew this but I'm being a bit O/C...
Now the "long way" part. Whichever Imprint you're interested in, you just have to enter it into the SEARCH box. But your
little gray cells have to know the Big 5/Imprint relationships. Easy for me: Penguin/DAW, Macmillan/TOR, Penguin/The Dial Press. Not so easy: Penguin/St. Martin's/Minotaur.
If for some reason you want to know the results for Pubs subtending the Big 5. As mentioned in an earlier post e.g., the fat Penguin takes NO queries, yet its Imprint DAW is very receptive.
Rarely, you'll enter an Imprint that you know is owned by one of the Big 5, yet doesn't show up in the database at all. That is the time to tap our great and powerful Wizard, Patrick, on the shoulder, and say the word "runcible" five times fast. This will fix the omission so long as your suggestion is both accurate and apt. I have submitted three (3!) updates as of yesterday.
I'll be sending more on a drib-drab, catch-as-catch-can basis. Please do not swamp the Wizard if you choose to do the same!
Once again, here is that
