Citebase Search is a semi-autonomous citation index for the free, online research literature. It harvests pre- and post- prints (most author self-archived) from OAI-PMH compliant archives, parses and links their references and indexes the metadata in a search engine.
Citebase contains articles from physics, maths, information science, and (published only) biomedical papers.
Please do not be discouraged if your papers fail to appear or have few or no citations.
Citebase's coverage and capabilities are based:
(1) only on those citing and cited papers that their authors have already archived in the source eprint archives,
(2) only on those of the cited papers that can currently be successfully linked,
(3) and, for arXiv, for now, on the usage/hit data for its UK-site only.
The literature available online is growing daily, but it is still only a tiny subset of the total current research literature across disciplines. (Hence the moral of this story is not that these capabilities are intrinsically limited, but that researchers should hurry and self-archive their papers so the coverage can be complete!)
A new potential measure of on-line impact, not available in the on-paper era, is usage, in the form of "hits." This measure is noisy (it can be inflated by automated web-crawlers, short-changed by intermediate caches, abused by deliberate self-hits from authors, and it can be undiscriminating between nonspecific site-browsing and item-specific reading) yet it seems to have some signal-value too, partly correlated with and partly independent of citation impact: http://opcit.eprints.org/opcitresearch.shtml
Web log usage data ("Full-text Downloads") currently covers only:
| Record Source | Period | Notes |
|---|---|---|
| arXiv.org | August 1999 - | Only accesses to the UK arXiv mirror. This does not include accesses to the other 17 mirror sites, including the main US-based arXiv.org site. |
| Biomed Central | None | |
| Cogprints | None | |
| ECS EPrints | March 2005 - | |
| Pubmed | None | |
| RCLis | None | |
| Soton EPrints | March 2005 - | Some weeks are missing in April due to server move. |
