I downloaded a great app on my phone (MyTouch, runs Android) that allows me to scan multiple pages and convert them into crystal clear PDF documents. It’s called CamScanner. It has a multi-page feature that lets you take pictures of page after page, while it patiently waits for you. Once you’re done, it converts them all into clean, high-contrast, pdf pages in one document. I then upload the document to Dropbox, directly from the app, and open it in iAnnotate on my iPad. Then I can annotate it to my heart’s content. This is a really liberating workflow that allows me to easily capture important pages from books and journals.
