In the past the best option to access annotations and highlights was to transfer a locally stored ‘my clippings’ file when connecting a Kindle to a PC. To further organise the output of the file, according to e-book and location in an e-book, there were options to upload the 'my clippings' file to clippings.io or to utilise a Calibre plug-in. Thankfully things have moved on since then and Amazon released an update that allows greater flexibility and options to externally store a user’s notebook. On a Kindle device the possibility of exporting a notebook to an external email is possible through first selecting reading settings and then notes (from notes there is an option to then email the notebook). Unfortunately, the ability to email notes and highlights applies to Amazon books and not personal e-books.
However, it is still possible to email and share a personal e-book's notebook to external accounts - e.g. Evernote and Onenote - via the Kindle application or Fire tablet. This is possible, as notes and highlights of e-books are stored in the Amazon cloud and automatically synced over different devices. Thus, a personal e-book's notebook would be available to export in the Kindle application when synced from, for example, a Kindle Paperwhite. The process of exporting the document is very easy and applies to both Fire tablets (Fire OS) and Kindle application - first tap on reading settings and then choose export a notebook; after choosing to export, it is then possible to send the notebook to external applications e.g. E-mail, Onenote, Evernote etc. A further useful feature is the ability to export utilising different citation styles (APA, Chicago Style, MLA or none).
