PubMed is probably the most important database used by scientists across the globe. Most researchers will routinely do a PubMed search to look for relevant literature on a monthly, if not weekly, basis. But how many of us really know how to use PubMed to its fullest extent? How much more efficient would our literature searches be if we just knew how to make the most out of PubMed? Luckily, NCBI, has put together a YouTube channel with detailed explanations on how to use many of their advanced products. Here is a video demonstrating how to use the PubMed Advanced Search Builder. Be sure to checkout the NCBI YouTube page for more great videos.
