There are two sources of references that I use quite frequently in preparing for didactics and presentations for teaching points. MD Consult and Uptodate. These are both resources that take original works and summarizes for physicians. They often take from multiple sources and are usually written by a few authors. In a way, they are articles themselves. They carry a lot of weight for physicians because of how concise it is. For Uptodate, it would be great to capture the article's reference just like any other journal article. For MD Consult, this is a little harder. They have their own search engine and pulls articles from everywhere. The problem is Zotero does not seem to be able to recognize the articles that MD consult pulls up.
