Orig­i­nal­ly pub­lished in 1993, The World Must Know is a stun­ning, skill­ful­ly orga­nized and pow­er­ful­ly writ­ten account of the Holo­caust as told in the Unit­ed States Holo­caust Memo­r­i­al Muse­um. Draw­ing on the museum’s exten­sive col­lec­tion of arti­facts, maps, films, music, archives and per­son­al tes­ti­monies and aug­ment­ed with over 200 peri­od pho­tographs, the book intro­duces the read­er to both the Holo­caust and to the muse­um in a most engag­ing fash­ion. The revised edi­tion is enhanced by new infor­ma­tion and insights based on archival infor­ma­tion made acces­si­ble to researchers after the col­lapse of the Sovi­et Union and East­ern and Cen­tral Euro­pean Com­mu­nist regimes and includes new pho­tographs, charts, a new sec­tion on the Holo­caust in Greece and an updat­ed bib­li­og­ra­phy. The book does not repli­cate the expe­ri­ence of the muse­um. Noth­ing can do that. It remains a mov­ing, often trans­form­ing expe­ri­ence for the mil­lions of peo­ple who vis­it it. But the book stands on its own both as an overview and an in-depth exam­i­na­tion of his­tor­i­cal events. It attempts to be mul­ti­dis­ci­pli­nary by incor­po­rat­ing the insights and approach­es of his­to­ri­ans, polit­i­cal sci­en­tists, philoso­phers, writ­ers, psy­chol­o­gists and the­olo­gians. Some of its most effec­tive nar­ra­tive sec­tions are punc­tu­at­ed by the per­son­al tes­ti­monies of sur­vivors, which are woven into the text so that his­to­ry, like the exhibits of the muse­um, is brought to life through the expe­ri­ences of peo­ple who endured this human tragedy. The writ­ing is crisp and com­pelling, the pho­tographs and charts are strik­ing and illu­mi­nat­ing and the book is a won­der­ful com­pli­ment and com­pan­ion to the muse­um whose mis­sion, dur­ing a time when eth­nic vio­lence, anti-Semi­tism and geno­cide con­tin­ue to plague the world, is as rel­e­vant as ever.
