去图书馆(和其他借电子书的图书馆) (Library To Go (and other libraries lending eBooks))

Now you can check out library books as eBooks without ever setting foot in a library. The Library To Go website mentioned here is for libraries in the Northern California area. Go to the website for a library near you to find out if they offer eBook lending and how to borrow eBooks from them.

现在,您无需踏入图书馆,就可以将图书馆书籍作为电子书签出。 此处提到的Library To Go网站是针对北加利福尼亚地区的图书馆的。 请访问您附近的图书馆的网站,以了解他们是否提供电子书借阅以及如何向他们借阅电子书。

Library To Go uses the Adobe Digital Editions software for eBooks and OverDrive Media Console for audiobooks. You can borrow eBooks in Kindle format (for U.S. libraries), EPUB, and PDF. Kindle books can be delivered to both Kindle devices and Kindle reading apps on other devices. EPUB eBooks have “reflowable” text that fits any screen, so they are good on most mobile devices. PDF eBooks have fixed text, but you can zoom in on the text to create a large-print eBook.

Library To Go将Adobe Digital Editions软件用于电子书,将OverDrive Media Console用于有声书。 您可以借用Kindle格式的电子书(适用于美国图书馆),EPUB和PDF。 Kindle书籍可以同时发送到Kindle设备和其他设备上的Kindle阅读应用程序。 EPUB电子书具有适合任何屏幕的“可重排”文本,因此在大多数移动设备上都很好用。 PDF电子书具有固定的文本,但是您可以放大文本以创建大字体电子书。

08b_library_to_go

Library To Go allows you to check out up to three titles and your cart will hold up to 15 titles. This differs, depending on the library. For example, the Ventura County Library in California (powered by OverDrive Media Console) allows you to check out up to five titles and your cart will hold up to seven titles. The lending period can vary from title to title. Titles are generally removed from your cart after 30 minutes so that other users can have the chance to check them out.

Library To Go允许您签出多达三个标题,并且您的购物车最多可以容纳15个标题。 这有所不同,具体取决于库。 例如,加利福尼亚州的文图拉县图书馆(由OverDrive Media Console支持)允许您签出多达五个标题,而您的购物车最多可以容纳七个标题。 贷款期限可能因标题而异。 通常,标题会在30分钟后从您的购物车中删除,以便其他用户可以将其签出。

On the Library To Go site, you can place up to four titles on hold at one time. They send you an email when a title becomes available. You have five days to check out your hold after we email you notification that it is available. On the Ventura County Library site, you can place up to five titles on hold at one time and you have four days to check out the books on hold once they become available.

在“要去图书馆”网站上,一次最多可以保留四个标题。 当标题可用时,他们会向您发送电子邮件。 在我们通过电子邮件向您发送通知后,您有五天的时间来查看您的保留状态。 在文图拉县图书馆网站上,您一次最多可以保留五个书名,并且一旦有可用书,您将有四天的时间来检查保留的书。

NOTE: Use the OverDrive service to find a public library in your area that allows you to check out books on your eReader. This is a relatively new service, so not all libraries are connected, yet. Check both the OverDrive site and your local library’s website to see if eBook rentals are available at your library. Also, be sure to check out the eBook lending policies for your local library.

注意:使用OverDrive服务在您所在的地区找到一个公共图书馆,使您可以在eReader上检出书籍。 这是一项相对较新的服务,因此尚未连接所有库。 检查OverDrive网站和您当地图书馆的网站,以查看图书馆是否提供电子书租借。 另外,请务必查看您当地图书馆的电子书借阅政策。

Once you reach $10 in credits, Lendle pays out a $10 Amazon gift card. The gift cards are paid in bulk, twice a month.

Lendle对于通过Lendle借出的每本图书向所有用户支付少量信用。 我们为每本书支付的价格因该书的价格,需求和供应而异。 借出一本书后,Lendle会等待整个21天的贷款期(借款人接受为7天,然后为贷款14天),然后再贷记给贷方。 一旦您获得10美元的信用额度,Lendle就会支付10美元的亚马逊礼品卡。 礼品卡每月两次批量支付。
