I add each week about 200 – 300 new download links to summaries and / or publications. Therefore, the number of files is increasing each weekend. The file names start with the date of the corresponding Saturday. Therefore, you can see immediately the date of the addon, e.g, 20210522, equivalent to the 22nd of May, 2021. The newest files are on the top. The older items are available in the Electronic Medical Library on a 4TB external 2.5″ USB 3.0 drive.
