Invenio (formerly CDSware) is a suite of applications that provides the framework and tools for building and managing an autonomous digital library server. It complies with the Open Archives Initiative metadata harvesting protocol (OAI-PMH) and uses MARC 21 as its underlying bibliographic standard. Its flexibility and performance make it a comprehensive solution for the management of document repositories of moderate to large size.
I, Librarian is a PDF manager or PDF organizer that allows individual researchers or a group of researchers to create an annotated collection of PDF articles. Users may build the virtual library collaboratively, thus sharing the workload of literature mining. It enables smart browsing and fast searching in reference data and PDF files, and includes an advanced tool for mining scientific literature from PubMed, PubMed Central, NASA ADS, arXiv, IEEE Xplore, and HighWire Press.
