包括很多的专业类、工程类、编程类、人文艺术类书籍。

有些朋友说有些链接不免费，也有些同学很客气的说“可能自己不会下载”。说第一个不能免费下载。我在这里说一下怎么下载，这些网站大部分是搜集大量电子书的，其网站本身服务器空间有限，因此都借助外边的存储空间存储书籍。
外网下载东西一般提供两个链接：“常规下载”和“高速下载”。
选择“常规下载”可能要等1分钟左右才能下，这个是免费的；
选择“高速下载”就得收费了。

个人觉得这些网站都很好，提供的书籍很多都是你在国内花钱买都未必买到的。而且新的专业书也很多。

自然，你不能说你非要选择“高速下载”，放弃“常速下载”，然后，你就说这些书籍下载都要收费吧？
