Pre-formatted citations

Helpful tip:  Citations formatted for you!


For any item (book, article, etc.) included in OneSearch, click on the title.  Then, you can get the citation by clicking on

on the right side of the screen.  Scroll down for different citation styles.

Click on the title of the source.  Look for a link that says "Cite" or "CiteNow" or "Citation Tools."

For pre-formatted citations for books, go to  Find the book you want to cite. Click on Cite/Export. Click on the + for the style you need (APA, MLA, etc.) Copy and paste the citation!

The free EasyBib app for iOS and Android allows you to capture bibliographic information about a book by scanning its barcode. It then generates a citation which you can email to yourself.

Help citing sources in databases

Citing full-text articles from online subscription databases

Look for the information you need to cite a full-text article at the top or bottom of the page, or look for an option to click to prepare the citation in multiple styles. (The link might say "Cite" or "Cite this article.") Make sure to note the name of the database. Or use a bibliographic manager, so you can export the citation directly to your personal database of sources.

In The Scott Foresman Handbook for Writers, see the section on "Sources from library subscription services" for the style you are using. (In the library reference section at REF 808.042 R929s)
