You should cite an UpToDate topic review as a chapter in a book titled UpToDate, edited by Ted Post, and published by UpToDate in Waltham, MA. Because our material is updated each year, you must always use the current year in your citation. There are no page numbers to cite. Below is an example of the correct format:

Marion DW. Pacing the diaphragm: Patient selection, evaluation, implantation, and complications. In: UpToDate, Post TW (Ed), UpToDate, Waltham, MA. (Accessed on January 04, 2018)

Searching for Royalty-free Images

OSUWexnerbloglogo2014Searching for royalty-free images is more improved when using Google search. This is extremely beneficial for many of our MedNet21 webcast presenters that are looking for images for their medical presentations. This tutorial will guide you through the process of locating images free of copyright restrictions.

First, open your web browser and navigate to the Google website.  Now, type in the item that you would like to search for.






Once the results of your search appear, click on the button or text labeled Images.

Now, click the button that says Tools.

Select Creative Commons licenses from the Usage Rights drop-down menu.

If any royalty-free images are available from your search, you should see them appear in the results. Also, Creative Commons licenses now appears for your selection.  You can use these images in most cases, but you’ll need to abide by the Creative Commons license for your image.  Learn more about Creative Commons licenses.

In addition to ensuring that you’re not using copyrighted images, it’s good to keep a record of the web page or URL that you obtained your image from.  This helps you to quickly confirm for others that your images are not copyrighted and are free to use for your presentations.
