We’ve already discussed the "Research" tool and how to use it to find and insert images into your document. But it can also help you find definitions, synonyms and antonyms using the "Dictionary" search. While each word’s dictionary entry is pretty small, the "Dictionary" search can save you the trouble of leaving your document to search another site, a real productivity killer.
Well-placed quotes can be a big help in driving your argument home, but general quotation searches can be unreliable. The "Quotes" search in the research sidebar will provide fewer but higher quality quotes results, and you can examine the sources for each quote to determine its reliability.
If you choose to include a quote in your document, select Insert from the Research sidebar. Again, Google Docs will automatically include a citation in your preferred format, this time linking back to the quote site in a footnote.
