No, I (theoretical solid state physicist) didn't know about NASA ADS, but it seems to cover most of the relevant literature (including arXiv and APS journals). So yes, an integration into I, Librarian would be great.

In CERN DS (with certainly a focus on high-energy physics) my papers are shown only up to 2006; so this database appears useless for me.

What the submitter needs (and I also need) is an organizer for scientific papers with an interface for standard fields such as authors, journal, title, doi, http links etc. I, Librarian seems to fulfill this need; unfortunately with direct interfaces (for retrieving pdf and meta information at the same time) only with pubmed.

If anybody knew of (or planned for) an adaptation to physics (with interfaces to arXiv.org, the APS journals and ideally other journals), I would be very interested (even as a paying customer).
