Handbook of proteins, by Ajit S.Brown, CRC Press, 1990; gives data on 2,000
proteins, incl. # chains, MW, pI, ext. coeff., source, and 5 residues of N-
and C-terminal sequences. However, data are incomplete and pI values are
given for only 15-25% of proteins. I find it useful but it is a VERY thin
book for the money (can't remember price).
