Ease of Use

MedlinePlus does not create unique content, instead providing numerous links to curated content from diverse resources. For some readers, the constant scrolling and jumping back and forth between websites may prove frustrating. And using the search bar pulls results from the entire MedlinePlus website, not just the heart disease section. However, the website as a whole provides users with dozens of relevant resources without overwhelming them.

Visual Design

MedlinePlus features a professional and simple visual design. Few images populate the pages here, but the topics explored often have links to relevant multimedia, especially videos. The site's use of color is subtle and pleasant, proving that a website doesn't need to be flashy in order to stand out visually.


The quality of materials collected on MedlinePlus is outstanding. Readers will find current, evidence-based materials that detail common topics related to heart disease. All topics in the medical encyclopedia are referenced. All other information comes from links to respected federal or speciality organizations, most of which are referenced.


The site's authors/editors are not identified. The linked websites occasionally credit authors, but not always. Among those organizations responsible for the MedlinePlus content include the highly credible National Library of Medicine, American Heart Association, National Cancer Institute, and American Cancer Society. And the website does a fantastic job keeping all the links up-to-date with review dates provided for readers.
