哦，我来说说这个吧。这其实是 Yin Zhangqi 告诉我的。一个是 Document Archive，它使用 Perl；另一个是 Document Database，使用 Php。它们的功能从介绍来看差不多，但是 Php 更“大众”一点。我可能会尝试安装一下。Document Database 的功能列表：

* User Account Management with groups for Admins and Users
* Entry of any current BibTeX Document type with context sensitive help function
* Simple search within any single or all fields
* Boolean Search with Query Builder (1.2)
* Last viewed list
* Emulates BibTeX layout for easy verification including limited support for foreign characters (1.2)
* Uploads of documents (read the Disclaimer)
* Uploads of files into a searchable filearea (1.2)
* BibTeX output for each entry
* User can share notes on documents (1.2)
* Supports multiple instances on the same machine (1.0.1)
* Robust and easy installation (1.0.1)

等我试过了，我可能会贴个安装说明什么的。
