Tip #71: Removing Clinical Trials Records from Embase.com and Cochrane CENTRAL

Image
A huge thanks to John Reynolds , MLIS, from the Louis Calder Memorial Library at the University of Miami Miller School of Medicine, who wrote this post! Embase (Elsevier’s Embase.com) has recently added large numbers of clinical trials records to their database and includes them in search results by default. Starting in May 2025 they added 500,000 records from ClinicalTrials.gov and continue to add new records. See their FAQ for more information. Similarly, Cochrane CENTRAL (Wiley) has been adding clinical trials registry records from ClinicalTrials.org and the WHO ICTRP since 2023.

Tip #29: Filtering by Date Added in Scopus

I've only seen this tip on a couple of pages, including this blog page ( https://christinaslisrant.scientopia.org/2014/04/29/se...
