On December 27, 2016, as this database reached its 10,000th entry, though its entry number is less because of the old decimal extensions used in the prior printed editions, I decided to add it in the "electronic resource" category. What distinguishes this site from the other "electronic resources" included under this category til this date is that it has been the work of only three people: Fielding Garrison, Leslie Morton, and myself, and it traces its origins back to 1912.  See About HistoryofMedicineandBiology.com.
