*86*, but what about GCR?  After all, GMRES is an incremental
 modification of GCR.  It also contains mispredictions like:

  "In practical implementation it is usually more suitable to replace
  the Gram-Schmidt algorithm of step 2 by the modified Gram-Schmidt
  algorithm"

If someone uses LGMRES, would we produce a citation only to Baker et al,
or also to Saad & Schultz?  What about the BiCG family, containing many
more variants that are slight variations on existing methods?  Or
identical methods that were published twice under different names?
