For those that might still have an interest, attached is a spreadsheet with the various phasing methods used to solve structures. As this information is captured as free text, one can see the variation in responses (772 different ways of responding to this question when we ran the SQL query). Next to each is the count for each response- there are a lot of singletons.

Subject: Re: [ccp4bb] See Jiang and Sweet ......Re: [ccp4bb] Structures determined: breakdown of methods
Thanks, John.
Of course whatever Jiang and I put in that paper is pretty old. The PDB
have been taking care of the Jiang and Sweet archive for some years. They
completely rewrote the code, and they have added some searches. The catch
in this case is that they are only synchrotron-based structures. Have look
here.
http://biosync.sbkb.org/stats.do?stats_sec=MAIN&stats_focus_lvl=GLBL
From here choose one of the structure galleries, for example Europe:
http://biosync.sbkb.org/stats.do?stats_sec=GALLRY&stats_focus_lvl=RGNL&stats_region=European
Then choose a beamline, say ID23-1:
http://biosync.sbkb.org/stats.do?stats_sec=GALLRY&stats_focus_lvl=BMLN&stats_site=ESRF&stats_bmln=ID23-1
Then, near the top of the page, see the line "Table of general information
(software, resolution, R-factors, etc) in tab delimited text format"
http://biosync.sbkb.org/biosync_pdbtext/measureESRFID23-1.txt
You'll get a table where the solution method and software follows the
PDB_ID. There's a RELEASE DATE at the end on which you may sort.
One catch is, this is one beamline at a time. Maybe there's a way to do a
direct query on PDB to get what you want all at once. That would resolve
the other catch that it's synchrotron-only structures.
