A while back, I read and enjoyed Daughter of Smoke and Bone. I then googled it and learned that a sequel was in the works, but the title and release date of the sequel hadn't been announced yet. Then I forgot about all it.
Fortunately, the sequel (entitled Days of Blood and Starlight - I haven't read it yet so no spoilers please) turned up on some of the Best Books of 2012 lists, so I was reminded of its existence and added it to my holds list. However, if it hadn't been mentioned in an article I read, I would never have thought to look it up again and would miss the opportunity to spend more time with the characters.
The same thing keeps happening with the Dexter series. I forget to look for new books and discover two have been written since I last checked, or I check for new books and find that there aren't any. I'd also be interested in reading whatever Malcolm Gladwell happens to write next, but he hasn't published in 3 years. I also think I'm going to keep reading the Inspector Gamache series once I catch up, but I don't know whether it's on a predictable publication schedule.
I don't want to subscribe to all the authors' newsletters, because in many cases I’m not actively involved in the fandom so I don't want all the promotional material about book signings and paperback release dates and media appearances. I just want to be informed when there's a new book to add to my holds list.
I think the library would be able to help me with this.
I'd like to be able to select an author or series out of the library catalogue, and have it automatically add any new title from that author or series to my holds list. Users who subscribed first get placed on the holds list first, and users would have the choice whether to add the title in active or inactive mode. That way I don't need to keep googling every author I'm interested in, then keep searching for upcoming titles until they show up in the library catalogue, and perhaps the library would have better data on interest in upcoming titles.
If this is all too complicated, maybe the library could just send out automated email alerts when a new title from an author or series you subscribe to has been added to the catalogue, and users could add it to their holds list themselves.
