Do you teach reading? Did you ever need to teach a lesson about a certain skill and draw a complete blank on which book to use? Boy, I have and I really wished I had a list of all the books I ever read and what skills I could teach with them. I totally get that you can use ANY book to teach almost ANY skill, but in my mind, there are books that lend themselves more easily to one (or more) skills than others. So with that in mind, I created a database. The database allows you to search for books based on the title or author or the level (either F and P or lexile, since that's what I use in my school district) but what makes mine different, is that it allows you to search by the skill you want to teach (either reading or writing). Once you've pulled up a book title, it also includes books that you can connect to it... like fiction or non fiction or books on the same topic or theme and sometimes books that you can compare and contrast.
I also thought, "Gees, what if you are looking for a book in a place that doesn't have wifi?", (which is like no where any more, but ok.) So I hired a guy to turn my database into an app. And now it's on itunes!
So here's a link to my website (in case you are interested). thebooksearch.net And here's a link to my app in itunes (in case this seems like a fills a need for you!)
