I've been trying out the Writer's Resource Base. At first glance it looks a bit old-fashioned, but from my limited experience with using it, it's not bad. There's a search box, and you can use quotation marks to narrow your search down.
For example, searching for "new journalism" led to 8 results whereas a search for new journalism led to over 700 results. (When it comes to search, fewer is usually better.)
One source of frustration is that there doesn't appear to be a way of changing the order in which the results appear. I'd have preferred reverse chronological, but I think it is organised by relevance. That sounds logical enough, but if you are searching for, say, self-publishing, it's likely that you would prefer the most up-to-date info.
Nevertheless, it's free, and it's specifically for writers, so I think this will be a good adjunct -- and perhaps even an alternative -- to Google.
In the title of this piece I included the phrase "and more". That refers to the fact that Mike Fleming, the person behind the WRB, has also created a fiction story organiser that is free to use. This looks pretty neat. I've been trying it out, and with a bit of tweaking and poetic licence, it can be used to organise a non-fiction book too.
These resources are definitely worth checking out.
