This book is sold subject to the conditions that it shall not, by ways of trade or otherwise, be lent, re-sold, hired out or otherwise circulated without the publisher's prior consent in any form of binding or cover other than that in which it is published and without a similar condition including this condition being imposed on the subsequent purchaser.
What does a similar condition refer to?
I need native speakers' help.
The text refers to itself. Anybody who loans, re-sells, or rents out the book must impose the same conditions as those in the text on the next owner. It's clumsily written, as whoever borrows or rents the book is not a "subsequent purchaser".
I am not a teacher.
