We are are looking for comments on the methodology for the **completeness** portion of this study. Please comment on Version 2. Please comment here or to Robyn Butcher, robynb@cadth.ca or Margaret Sampson, msampson@cheo.on.ca We also invite your comments on the second portion of this validation study - **currency**. We will select journals, monitor them for the emergence of a new article relevant to COVID-19, and then track the selected articles to see when they appear in the COVID-19 collections. We would like ideas on how best to select the journals to monitor- for example: - Should we be sampling both general and specialty journals? - Should we be watching preprint servers or only accepted journal articles? - Should we be covering different languages? Regions of the world? - Should try to include journals that publish few articles on COVID-19 or higher volume journals, or a mix? - What other parameters might be important to cover or balance?
