IOP 新弄了个 EprintWeb，内容完全基于 arXiv。那么它与 arXiv 有何不同呢？EprintWeb 的说明：

We have focused on your experience as a user, and have addressed issues of navigation, searching, personalisation and presentation, in order to enhance that experience. We have also introduced reference linking across the entire content, and enhanced searching on all key fields, including institutional address.
