The short answer is yes, they are legal.
However, a recent lawsuit has been filed against Internet Archive so it may help to understand their e-book service model and the issues being raised against them.
On June 1, 2020 the Author’s Guild filed a copyright infringement lawsuit against Internet Archive. The lawsuit was provoked by Internet Archive’s National Emergency Library which was launched in March 2020 to address the needs of students and educators as they shifted to remote teaching and learning due to the Covid-19 pandemic. This emergency program suspended wait lists allowing anyone in the world unlimited simultaneous access to their digitized texts. (See Internet Archive's response to the lawsuit)
On June 16, 2020, Internet Archive closed its National Emergency Library and reverted back to what is referred to as a “controlled digital lending” model for its Open Library collection. This model, which has been in effect for over a decade, allows libraries to treat a digitized print book like an actual print book borrowed from a library rather than an e-book that multiple people can access simultaneously. Under controlled digital lending, Internet Archive e-books can only be viewed by one person at a time, like a print book would be. Others will have to wait to gain access until the loan period ends or the e-book is returned.
When Internet Archive closed their emergency library in mid-June 2020, they shortened the loan period to 1 hour (down from 14 days) to allow as many people as possible to have access to their digitized books while still adhering to the controlled digital lending model. If there are two or more digital copies of a book, there will be an option to borrow the book for 14 days or 1 hour. If no one else is waiting after the loan period ends, the e-book can be checked out again by the same person.
