The section of the original image containing the logo. This is the amount needed to identify the logo, and compare it with other logos to attempt to identify the publisher, data of publication, imprint, or other bibliographic data.

As logos are almost invariably copyrighted, the image is not replaceable by free content; any other image that shows the logo would also be copyrighted, and any version that is not true to the original would be inadequate for identification. Moreover, logos are generally intended to be reproduced to identify the logo-owner and the owner's products.

The use of this image, in connection with research into the bibliographic status of various publications, as part of the ISFDB, a non-profit bibliographic reference work, on servers located within the United States, is believed to constitute Fair Use within the meaning of United States copyright law.

Reusers of the ISFDB's content should take care to be sure that their use conforms to applicable copyright law -- not all such uses will constitute fair use, and copyright law varies significantly in different nations.
