Google Drive Add-ons:
Google Drive users now have the ability to incorporate "Add-ons" to add features to various Google Apps. One of the most useful is the "Easy Bib" add-on.
To install an Add-on, open a blank Google document and then click on "Add-ons" (highlighted in yellow above) and then "get add-ons." That will take you to a mind-boggling array of options. Almost all of them operate on the "freemium" model, which means they provide some basic features for free and offer additional features for a cost.
Once EasyBib is installed it will be available in all Google documents that the user edits in the future. To open EasyBib, click on "Add-ons," "EasyBib," and then "Manage Bibliography" (even if it's your first entry).
At that point, a sidebar opens and the author can enter a book or journal title or a website address and, in most cases, it will automatically create a works cited entry. The author can choose between MLA, APA, or Chicago styles. The example below is from a source found on "Google Books."
As previously stated, there are a huge number of options for add-ons. there are flow chart designers, mind map makers, formula editors, translators, rhyme makers, and much, much more. If you find one that is particularly useful, feel free to post it in a comment below.
