The information flow, especially in Life Sciences, accelerates exponentially. We are all facing the challenge of how to keep pace and not to get lost in all the data. Virtually every scientific journal offers publications in a digital form. We possess hundreds or even thousands of articles as PDF files but to find one that we need is increasingly difficult.

What does it do? I, Librarian is a PDF manager or PDF organizer, which enables individual researchers or a small group of researchers to create an annotated virtual library of articles in portable document format (PDF). Users may build the virtual library together, and then browse and search articles by words or phrases. In other words, you will have instant access to the full text of the article, which you identified in seconds. By installing I, Librarian, you will build your local web site with a practical environment to work with your PDF files. In addition, you will gain an advanced tool to mine scientific literature from PubMed, PubMed Central, NASA ADS, arXiv, and HighWire Press.

Back-end. I, Librarian is written in PHP and stores all PDF annotations in an SQLite database. There is no need for MySQL, so installation and backups are very easy.
