I cannot find the older electronic Dragon Issues compiled as PDFs. Does anyone have a link to where one can download them? The WotC website is rather unhelpful with finding anything.
#364 is available at http://wizards.com/default.asp?x=dnd/drtoc/364 (click where it says "Download complete issue now").
Archive is located at http://wizards.com/default.asp?x=dnd/4mag/archive.
Unfortunately, WotC didn't want to take the time to make complete PDFs of the interregnum issues, so the only one available that way is the first one, #360. Numbers 361, 362 and 363 are individual articles only. Grrrrrr.
Hopefully, they'll take the time to go back and make PDF compilations for each of the other issues (and for Dungeon too). It's a long shot, but it could happen.
