Goodreads is a great website for keeping track of the books you have read, own, want to read, are reading, etc. You can organize the books in bookshelfs that you name to best reflect the way you want to organize your books, which can include putting books in multiple bookshelves. However, a book always has to also be in your Read, To Read, or Currently Reading of the site’s automatic bookshelves. The Goodreads iPhone app is a great way to access your bookshelves and manage them on the go.
The Goodreads iPhone app is especially useful for adding new books to your to read or currently reading bookshelves. You can add them simply by scanning the book’s barcode. This is convenient for quickly adding a book before you start reading it. It is also great for adding books that look interesting to your to read, but you do not want to buy right away. You can even scan them in batches and then add them all at once to your to read bookshelf or other bookshelves.
This is great for when browsing a bookstore that sells new books like Borders and you want to try to get the books cheaper used at one of Tucson’s Bookmans locations or buy them as an e-book when you get home through one of the Google eBook shops offered by local Tucson Bookstores. I loved using it at the Tucson Festival of Books to add books to my to read shelf, since there was way too many good books to buy in one weekend. The barcode scanning is also useful if you want to add your personal book collection to the site quickly.
The Goodreads iPhone app also has other features beyond the barcode scanning, but the barcode scanning is what makes it my favorite book app. Goodreads is also sort of a book social network, so if you are into that aspect you can catch up on your friends latest reviews, books their reading, etc. from the app, but I do not use that aspect of Goodreads, so not sure if the app does this aspect well.
The main other part of the app I use is the Explore tab, which has an Events near me search that can be fun for finding book events to attend, but it does not show that many of the Tucson book events and a Tucson zipcode search is usually a bunch of Phoenix area events, so the near me is quite broad and cannot be narrowed down to a certain mile radius.
Note: There is also a plain Goodreads Scanner app that is just the scanning aspect of the Goodreads app and also does not require a Goodreads account. Might be preferable for some, but both apps are free and Goodreads accounts are free and there are many additional features of the app and site (book giveways!) that makes the Goodreads app more useful than just the scanner.
