The U.S. Library of Congress Copyright Office is asking a question: “whether persons filing the electronic-only preregistration form prescribed by the Copyright Office will experience difficulties if it is necessary to use Microsoft's Internet Explorer web browser in order to preregister a work”. No, I’m not making this up. Comments are called for, and have to be sent (five copies!) by snail mail; the address is behind the link above. Thanks to Beth Macknik for the heads-up.
