对于我们很多人来说，电子书的普及（和可用性）的上升是一件非常好的事情。现在可以在一个平装书大小的包装中容纳整个图书馆的书籍，这对于假期和其他旅行特别有用。您不再需要决定随身携带哪些书籍。只需拿起您的Nook或Kindle，然后将它们全部拿走！
然而，让个人对电子书感到失望的一件事是其中有多少没有封面艺术。如果您去书店购买 Orson Scott Card's Enchantment，您会看到这个封面。
另一方面，如果您购买了 EBook of Enchantment， 您将获得此书。
不多比较。对于我们这些习惯于浏览封面艺术的人来说，有点失望。与许多音乐专辑封面艺术不同，可以从专辑艺术交换(Album Art Exchange)等地方轻松获取，没有书籍封面的公共档案。您可能会找到专门针对特定作者或特定艺术家的网站，但没有任何网站能接近涵盖“所有”书籍。虽然一些出版商网站会有高分辨率的艺术品，但很多都没有。
值得庆幸的是，就像可以从Google Play音乐商店（以前的 Android市场商店(Market Store)）下载高质量的专辑封面一样，您可以使用Google Play书店获得非常适合插入电子书的高分辨率艺术品。虽然您不会找到每本书的艺术品，但您会找到大量的艺术品。这是它的工作原理。
下载高分辨率书籍封面艺术(Download High Resolution Book Cover Art)
我们将使用Enchantment作为示例，但您当然可以使用任何您想要的书。
首先，前往Google Play 书店(Google Play book store)。
接下来，搜索您有兴趣寻找封面艺术的书；如前所述，我们将使用 Orson Scott Card 的Enchantment，因为我们知道存在高分辨率艺术品，但您可以随意搜索您想要的任何书籍。您现在应该看到一个结果页面。
继续并单击正确的结果，这将带您进入该产品的页面。
现在右键单击小封面艺术缩略图并选择查看图像(View Image)选项。在Chrome中，右键单击图像并选择在新选项卡中打开图像( Open image in a new tab)。
您现在应该会看到缩略图（在新版本的Firefox中，它将以黑色背景显示，如下所示）。
虽然这显然太小而无用，但它的URL确实为我们提供了一种访问高分辨率艺术品（如果有）的简单方法。转到URL栏并突出显示URL，然后转到URL的最后。您应该会看到类似https://books.google.com/books/content/images/frontcover/-rUACwAAQBAJ?fife=w200-h300的内容 ，如上所示。
要获得高分辨率艺术品，我们只需将宽度和高度部分更改为其他内容。在这种情况下，w=800 和 h=900 将为我们提供更高质量的艺术品。不幸的是，没有办法知道你能走多高。只需继续尝试更大的值，直到获得所需的大小。
完成此操作后，按 Enter(Enter)以加载新URL。如果存在高分辨率艺术品，您现在应该可以看到它。
现在您只需下载艺术作品，然后使用您喜欢的程序（例如Sigil或Calibre）将其插入您喜欢的电子书。享受！
Download High Resolution Book Cover Art
For a lot of us, the rіse in рopularity (аnd avaіlability) of eBooks has been a very gоod thing. Now it’s possible to hоld an entire library of bоoks in a package the size of a paperback, which is especially great for vacations and other trips. No longer do you need to decіde which books to take along with you. Simply grab your Nook or Kindle, and take them all!
One thing, however, that’s been personally disappointing with eBooks is how many of them don’t come with cover art. If you go into a bookstore and purchase Orson Scott Card’s Enchantment, you’ll see this cover.
If, on the other hand, you purchase the eBook of Enchantment, you’ll get this instead.
Not much comparison. And for those of us who are used to browsing by cover art, a bit of a disappointment. And unlike much music album cover art, which can easily be grabbed from places like Album Art Exchange, there is no public archive of book covers. You may find websites devoted to a particular author, or a specific artist, but nothing that would come close to covering “all” books. And while some publisher websites will have high resolution artwork, many do not.
Thankfully, just as it’s possible to download high quality album art from the Google Play music store (formerly the Android Market Store), you can use the Google Play book store to get high resolution artwork perfectly suitable for inserting into your ebook. And while you won’t find every book’s artwork, you will find a large number of them. Here’s how it works.
Download High Resolution Book Cover Art
We’ll be using Enchantment as our example, but you can – of course – use any book you want.
First, head to the Google Play book store.
Next, search for the book you’re interested in finding cover art for; as mentioned, we’ll use Orson Scott Card’s Enchantment, as we know high resolution artwork is present, but feel free to search for whatever book you want. You should now be shown a results page.
Go ahead and click the correct result, which will take you to that product’s page.
Now right-click the small cover art thumbnail and choose the View Image option. In Chrome, right-click on the image and choose Open image in a new tab.
You should now see the thumbnail image (in new versions of Firefox it will be shown against a black background, as you can see below).
While this is obviously too small to be useful, but the URL of this does give us an easy way to access high resolution artwork, if available. Go to the URL bar and highlight the URL, then go to the very end of the URL. You should see something like https://books.google.com/books/content/images/frontcover/-rUACwAAQBAJ?fife=w200-h300 as shown above.
To get high resolution artwork, we simply need to change the width and height part to something else. In this case, w=800 and h=900 will give us much higher quality artwork. Unfortunately, there is no way to know how high you can go. Just keep trying larger values until you get the size you want.
Once you’ve done this, hit Enter to load the new URL. If high resolution artwork exists, you should now see it.
Now you simply need to download the art, then use your favorite program (such as Sigil or Calibre) to insert it into your favorite eBook. Enjoy!
