Printing Information

REF1, REF2, and REF 3 have distinct printings.
 

REF1 Dungeon Master's Screen

• First (1985):  A paper cover (featuring the artwork from the Fifth printing of the DMs Guide, and having player character ability summaries on the back), enclosing two separate, 3-panel cardstock screens: a DMs Screen (same artwork as the cover), and a Players Reference Screen (artwork from the Eighth printing of the Players Handbook).  TSR stock #9146.  Rear cover has no ISBN above the bar code, and has the price ($6.00) on the lower right.  Designated as the Seventh printing on our DM Screen page.
   
• Second:  Identical to the First print, but has ISBN above the bar code (rear cover center), and has no price in the lower rear right.  Designated as the Eighth printing on our DM Screen page (thanks to Michael Deaton for this info).
   
• Third (1989):  New cover artwork, and now just a single cardstock DMs screen.  Angled TSR logo.  TSR stock #9263.  Includes the mini-module Terrible Trouble at Tragidore (which also has the Angled TSR logo), by Bruce and Jean Rabe, 16 pgs, for levels 5-8.  Designated as the Ninth printing on our DM Screen page.
   
• Fourth (1992?):   Identical to the Third printing, but now features the Gold Angled TSR logo (as does the included mini-module).  Designated as the Tenth printing on our DM Screen page.
   
• Fifth-Seventh:  Unknown.  As the Eighth printing of REF1 is the only print we've seen which actually states which print it is, these printings are hypotheticals only.
   
• Eighth (Feb 1994):  Identical to the Third print, but now features the TSR Dragon logo (as does the included mini-module).  Has "Eighth Printing, Feb 1994" on back cover.  Designated as the Eleventh printing on our DM Screen page.  Thanks to Linda Curtin for this info.

REF2 Character Record Sheets

• First (1986):  Basically an excuse to give the Character Record Sheets new cover art, in line with the redesign of the AD&D manuals (orange spine).  Orange band across the top.  Includes "spell planner" sheets.  Labeled as the 1986 AD&D character sheets on our Character Record Sheet page.
   
• Second (1989?):  Upgraded the sheets to 2nd Edition AD&D conventions, and changed the cover art.  Black cover, AD&D 2nd Edition logo.  Sheets are green-on-white (though a variation has been reported, with the green ink inside the information boxes, making them hard to read -- thanks to John Justice for this info).  Labeled as the 1989 AD&D character sheets on our Character Record Sheet page.

REF 3 Book of Lairs

• First:  Angled TSR logo.
   
• Second:  Gold Angled TSR logo.  (Thanks to Neville Ridley-Smith for this info).

REF6 Rogues Gallery is labeled the Sixth printing on our DM Aids page.

Thanks to Adrian Newman for scans of REF1 (Third print) and REF6.

All of these items are fairly common; the "encounter books" (REF3, REF4, REF5) are rather popular.
