If you manage an important amount of bibliographic references Memento is a very interesting alternative among other online tools. Some of its features are
- Add articles from URLs —Pubmed, Nature, etc— from files —BibTeX, RIS and more— and manually
- Organize your collection by Author and by Keywords
- Write reports linking selected articles
- Make watchlists
- Export to BibTeX and MS Word 2007 XML
- Share, Add to Cart, Add to Reports, Delete and Comment entries
- Sort articles by Title, Year, etc
- Explore graphically articles, tags and authors
- Edit article fields
- Search article in Citeseer, HighWire and more
- Last but not least, a competent and responsive developer supporting it. Thank you Ritesh Agrawal!
