Summary edit
| Description |
This is the front cover art for the book Compilers: Principles, Techniques, and Tools written by Alfred V. Aho, Monica S. Lam, Ravi Sethi, and Jeffrey D. Ullman. The book cover art copyright is believed to belong to the publisher, Pearson Education, Inc, or the cover artist. |
|---|---|
| Source |
Derived from a digital capture (photo/scan) of the book cover (creator of this digital version is irrelevant as the copyright in all equivalent images is still held by the same party). Copyright held by the publisher or the artist. Claimed as fair use regardless. |
| Article | |
| Portion used |
The entire front cover. Because the image is a book cover, a form of product packaging, the entire image is needed to identify the product, properly convey the meaning and branding intended, and avoid tarnishing or misrepresenting the image. |
| Low resolution? |
The copy is of sufficient resolution for commentary and identification but lower resolution than the original book cover. Copies made from it will be of inferior quality, unsuitable as artwork on pirate versions or other uses that would compete with the commercial purpose of the original artwork. |
| Purpose of use |
Main infobox. The image is used for identification in the context of critical commentary of the work for which it serves as cover art. It makes a significant contribution to the user's understanding of the article, which could not practically be conveyed by words alone. The image is placed in the infobox at the top of the article discussing the work, to show the primary visual image associated with the work, and to help the user quickly identify the work and know they have found what they are looking for. Use for this purpose does not compete with the purposes of the original work, namely the book cover creator's ability to provide book cover design services and in turn marketing books to the public. |
| Replaceable? |
As a book cover, the image is not replaceable by free content; any other image that shows the packaging of the book would also be copyrighted, and any version that is not true to the original would be inadequate for identification or commentary. Using a different image in the infobox would be misleading as to the identity of the work. |
