All our books – and all other items on the site – are free online. There is no sign-up to use Century Past.
Books on the site not in the public domain (most books published since 1925) are nearly all at the Internet Archive, so you will need a free account there to read them. Here’s their info about borrowing books.
Update: A 2023 court ruling required Internet Archive to discontinue lending books that are available for sale electronically. Many recently published books on Century Past are now unavailable. You can filter out unavailable books from our ‘collections’ by checking the ‘Lending Library’ box under ‘Availability’ in the left column.
