NIST has released the 2020 Edition of its MS Library and Search Software. This version has the fastest growth rates since their inception. The EI library contains spectra of over 306K compounds, an increase of nearly 40K from the 2020 version. The RI library has a corresponding increase. The Tandem (MS/MS) library doubles in coverage, with the number of compounds increasing to over 27K, including 1.2M spectra and 288K precursor ions.
