 WARSAW, Poland (AP) — Historians in Poland have put online what they say is the most complete list of Nazi SS commanders and guards at the Auschwitz concentration camp in hopes some of them can still be brought to justice. 
 
 The state-run Institute of National Remembrance said Monday that the SS KL Auschwitz Garrison list is based on data from archives in Poland, Germany, Austria, the United States and, to a limited extent, Russia, where archives remain mostly inaccessible. 
 
 The work of historian Aleksander Lasik, the institute and the Auschwitz-Birkenau Memorial, it has more than 8,500 entries. It is based on a list that Lasik built during more than 30 years of archival research. 
 
 "The world justice system has failed and I'm doing what a historian should do: expose the responsible individuals as war criminals," Lasik said. 
 
 Up to 200 former guards at the German death camp could still be living, he said. 
 
 Historians estimate that some 12 percent of Auschwitz guards were tried by courts in Poland and elsewhere. 
 
 Lasik's full database includes more than 25,000 names of guards from various German-run camps. The list is not complete and his search continues, Lasik told The Associated Press. 
 
 The online list of Auschwitz guards and commanders is written in Polish, English and German. Most entries include the date and place of birth, nationality, education, military service and party affiliation. Some have a photo attached. Judicial documents are included when the person stood trial in Poland. 
 
 For example, the entry for Rudolf Hoess, the camp's commander from 1940-43, has a photocopy of the death sentence he was handed by a court in Krakow, Poland, in 1947. 
 
 The dates of service at Auschwitz are being verified pending publication. 
 
 Nazi hunter Efraim Zuroff said the publication of the names is "very important and the right thing to do" and can have "practical implications" if Nazi crime investigators in Germany were unaware of some of the names. 
 
 It is estimated that from 1940-45, Nazi Germans killed some 1.1 million people in the death camp that they operated in occupied Poland. 
 
 Some 1 million of the victims were European Jews, up to 75,000 were Poles, some 21,000 were Roma and approximately 15,000 were Soviet prisoners of war. ||||| Image caption Posters displayed in Berlin, Hamburg and Cologne say "late, but not too late" 
 
 A poster campaign has launched in Germany aimed at tracking down the last surviving Nazi war criminals and bringing them to justice. 
 
 Some 2,000 posters showing the entrance to the Nazi Auschwitz death camp and asking people to come forward with information have been displayed in Berlin, Hamburg and Cologne. 
 
 The US-based Simon Wiesenthal Center offers rewards for useful information. 
 
 It estimates there to be 60 people alive in Germany fit to stand trial. 
 
 Some are suspected of having served as guards at Nazi death camps or being members of death squads responsible for mass killings, particularly early on in the war. 
 
 "Unfortunately, very few people who committed the crimes had to pay for them," leading international Nazi hunter and the centre's Jerusalem branch director, Efraim Zuroff, said. 
 
 "The passage of time in no way diminishes the crimes."

 Simon Wiesenthal Center: Most Wanted 
 
 As part of its "Operation Last Chance II" project, the centre is offering rewards of up to 25,000 euros (£21,500; $33,080) for information which helps to prosecute war criminals in Germany. 
 
 The centre, which is one of the largest Jewish human rights organisations, is asking for tip-offs via a hotline it has set up. 
 
 The posters depict a black and white photo of the railway tracks leading into Auschwitz and say in German: "Late, but not too late. Millions of innocents were murdered by Nazi war criminals. Some of the perpetrators are free and alive. Help us take them to court." 
 
 Auschwitz, in occupied Poland, was the biggest Nazi death camp where more than 1.1 million people, most of them Jews, were murdered. 
 
 Legal precedent 
 
 The poster campaign comes two years after the conviction of Ukrainian-born John Demjanjuk for his role as a Nazi guard at the Sobibor death camp. 
 
 Demjanjuk, who died in March 2012 at the age of 91, was sentenced to five years in prison in 2011 based solely on his service in the camp. 
 
 The centre says his conviction set a precedent allowing German prosecutors to reopen hundreds of investigations and prosecute former camp guards as accessories to murder, even if there was no proof the defendants personally killed anyone. 
 
 Germans are divided between those who think war criminals should be pursued to the grave and those, often younger people, who say the crimes are remote from present-day Germany, says the BBC's Stephen Evans. 
 
 In May, a 93-year-old former Auschwitz guard was arrested in southern Germany, accused of participating in the mass murder and persecution of innocent civilians, primarily Jews, between October 1941 and 1945.

 The arrests came five months after federal authorities announced they would investigate former guards at Auschwitz and other Nazi-era death camps. Their effort was inspired by the precedent-setting trial of former Ohio autoworker John Demjanjuk, who died in 2012 in a Bavarian nursing home while appealing his conviction on charges he served at the Sobibor camp. 
 
 "This is a major step," said Efraim Zuroff, the head Nazi hunter at the Simon Wiesenthal Center in Jerusalem, when told of the arrests. "Given the advanced age of the defendants, every effort should be made to expedite their prosecution." 
 
 Ukrainian-born Demjanjuk was the first person convicted in Germany solely on the basis of serving as a camp guard, with no evidence of involvement in any specific killing. 
 
 Munich prosecutors successfully argued that anyone who was involved in operating a death camp was an accessory to murder. Demjanjuk maintained he had been mistaken for someone else and never served as a guard. 
 
 Following the Munich precedent, Germany's special federal prosecutors' office responsible for investigating Nazi war crimes announced in September it was recommending charges against about 30 suspected former Auschwitz guards. State prosecutors since have worked to build cases. 
 
 The three men arrested, aged 88, 92 and 94, all live in state of Baden Wuerttemberg in southwest Germany. They were taken to a prison hospital, Stuttgart prosecutors' spokeswoman Claudia Krauth said. 
 
 Krauth said officials had yet to uncover enough evidence to merit the arrests of three other suspects aged 94, 91 and 90. 
 
 She said authorities seized "diverse papers and documents from the Nazi era" from the suspects' homes. She declined to provide details. 
 
 Five men made no statements, while the 88-year-old admitted being a guard at Auschwitz but denied committing any crimes, Krauth said. 
 
 Prosecutors in Frankfurt said more documents and photographs were seized during raids on the homes of two men aged 89 and 92 in the neighboring state of Hesse. A spokeswoman, Doris Mueller-Scheu, said neither suspect was arrested nor made statements. 
 
 In North Rhine-Westphalia, state police said they raided the apartment of a 92-year-old man who admitted being an Auschwitz guard but denied participating in any crimes. They found no incriminating material during the search. 
 
 The Nazis built six main death camps, all in occupied Poland: Auschwitz, Belzec, Chelmno, Majdanek, Sobibor and Treblinka. 
 
 About 1.5 million people, primarily Jews, were killed at Auschwitz from 1940 to 1945. Overall, about 6 million Jews died in the Holocaust. 
 
 Since handing off the Auschwitz cases to state prosecutors, federal authorities say they are focusing on identifying guards from other camps, starting with Majdanek. Results of that investigation are expected in a few months.
