The Internet Archive has temporarily suspended all wait lists, allowing you to immediately check out any of the 1.4 million books currently in their lending library. Until June 30th or the end of the US national emergency (whichever comes later), every borrowable book will be immediately accessible by anyone—creating, in effect, a National Emergency Library.
