Here is a resource that might be of use to educators and also to homeschooling parents.
In a March 24 post, Announcing a National Emergency Library to Provide Digitized Books to Students and the Public, the Internet Archive launched its National Emergency Library initiative, saying:
To address our unprecedented global and immediate need for access to reading and research materials, as of today, March 24, 2020, the Internet Archive will suspend waitlists for the 1.4 million (and growing) books in our lending library by creating a National Emergency Library to serve the nation’s displaced learners. This suspension will run through June 30, 2020, or the end of the US national emergency, whichever is later.
The library is here, and the FAQ is here.
According to the FAQ, the library is meant to meet a specific need for educational resources by schools, colleges, and universities in the United States, but it is available for use by anyone around the world. This comes at a time when, globally, 1 in 5 classrooms have been closed as a result of policy-makers' response to the COVID-19 pandemic.
