Is there online OpenData around mass spectrometry, and in particular EI (or other) mass spectra of organic molecules? I know of the NIST Chemistry WebBook, but do not believe that data can be redistributed.

From Tobias Kind:
If you talk about reference spectra with annotated structures. Few very few. In principle none, considering that there should be millions of datasets: These are services were you can download MS data for free:
Many other useful services only allow online queries, they are free to use but you can not bulk download data. There are other small databases, for EI-MS and MS/MS. My library will be free after publications (CC-BY).
