PREFACEOn September8, 2003, Edgar Holladay passed rom our ranks. This Anthologt is one of hisworks. He spentnrany years selectingand, in a large number of cases, evisitg the bestall U.S. corposers. Included here are 241 composers. The number of problemseachcorrposer,he felt, indicates heproportional contribution and/or significanceofProblems with a "v" after the date are versions; while "ev" indicates an editorial version -ofthese appearing for the first time. It is uncertain whether problems quoted fromAmericanNutsare original or were quoted from other sources. Unfortunately, and for unclear reasons,not to include any rankings of all Honorable Mentions and Commendations, nor anyor memoriams which were originally attached.

The move symbol "-" representsa random move or sirrple removal. The Keys are in bold"*" standsfor mate. "S" standsfor Knight. While Directrnates were mainly preferred,high-quality, unorthodox t5pes were selected to fairly embody the broad range ofcorrposing tastes.Here is a brief (incomplete) descriptionof each: In a Selfrnate Sf),plays to force Black to give mate. Reflexmates (R*) are similar to Selfrnates,except ifcanmate n one,hemust do so. In the Helpmate (H*), Black movesfirst and both sideso help White give mate. Only two fairy piecesare represented ere: I ) theGrasshoppermoveson queen-lines o ump over any manonto the next square, o occupy,check or capture;Orphan (@) is a dummy unit, until attacked by an enemypiece, then acquiring thepowerof suchpiece(s). ln a Duplex, both White and Black move frst (one solution byto meetthe stipulation (colors reversed). Maximummers (Max.) means hat Black musthis longest geometric move. Stalemates :) require no checkrnate,but only stalemate.An(*) indicates Set-play. In Circe chess,a capturedman is returned to its starting squareofcolor, if unoccupied; while a captured Pawn is returned to its samefile starting square,In Seriesmovers, the starting sideplays ,-consecutive moves to reachthe desiredSeveralproblemsrequire retro-analysis,which means, ooking backward to theplay thatto the diagramedPosition'

However, he insisted hat suchdata or this collectionaminimurrr Perhaps, n the end,he intendedthat this chronological assemblage houldor itse$ asequalsamong equalsacross ime.
