My Take
Notable is a great option when you want to interact with a PDF in a web-based environment. As a PDF viewer, it's clean, has search capabilities, and allows the reader to adjust text size with a zoom tool. As an annotation tool, you can select and highlight text, add text onto the page, include margin comments, and use the underline or strikethrough formatting options on the document. The annotation version can be printed, exported/saved to Google Drive or your computer, and shared via link with others for collaboration (if uploaded to Notable). The Notable version can also be embedded on a web page where others can respond to comments in the margins. The presentation mode is a nice option for displaying on a projector, and the flexibility of using this with PDFs on the web or stored in Google Drive or a computer make this a powerful way to read and work with PDFs.
How I Use It
When working with text, having students interact with the content by annotating can support a deeper understanding of the material. In digital or online environments, PDFs are a very popular format for articles and papers, but they don't lend themselves natively to reader interaction. Notable is a good tool for highlighting, adding notes, and text boxes onto a PDF. In the classroom, students can use Notable to annotate a PDF that they find on the web, have stored in Google Drive, or on their local computer. Marked up versions can be shared via link or embed code, and the Chrome extension can be used as both a PDF viewer and an annotation solution. Notable would also be a good tool to use with colleagues when reading PDF articles together for professional development or collaboration.
