Advance reading copy

An advance reading copy, or ARC, is a near-final version of a book's script that is released to a small number of readers, including booksellers, journalists, and sometimes certain celebrities.
Baen Books publishes electronic advance reading copies, or eARCs, in its ebook store, sometimes months before the book is officially released in print and ebook format. The information in these eARCs is considered canonical by the Honorverse Wiki.
