For anyone who remembers that we ever had free Washington Post access, I’m writing to let you know that we no longer do. A bunch of years ago, it was possible to register with a .edu address to get 25 free articles per month. Arabella found this page which indicates that the opportunity is still available for .gov and .mil, but not .edu  (https://helpcenter.washingtonpost.com/hc/en-us/articles/115007248227-Start-a-free-subscription-with-a-valid-gov-or-mil-email-address).

The lib/its blog post that publicized this access has been deleted.
