Wikipedia:Articles for deletion/Is the Holocaust Unique?
1st i had a look at WorldCat and see https://www.worldcat.org/title/is-the-holocaust-unique-perspectives-on-comparative-genocide/oclc/830350009?referer=br&ht=edition that this book is held in around 1400 libraries with multiple editions (don't know why so many libraries have it if not notable - maybe just popular?:)), then googling the name and "book reviews" there appears to be multiple reviews ie. ''German Politics and Society'' - https://search.proquest.com/openview/9d79e9a72fe2f31dc6faf2e706c07620/1?pq-origsite=gscholar&cbl=1816898 here, ''History: Review of New Books'' - https://www.tandfonline.com/doi/abs/10.1080/03612759.1997.10525337 here, ''Shofar (journal)|Shofar: An Interdisciplinary Journal of Jewish Studies'' - https://muse.jhu.edu/article/472391/summary here, ''The European Legacy'' - https://philpapers.org/rec/HARITH here, United States Holocaust Memorial Museum|Museum Fellowship Book Reviews - http://mandelproject.us/van%20Pilsum_rev.htm here, ''Choice: Current Reviews for Academic Libraries'' - https://bepl.ent.sirsi.net/client/en_US/default/search/detailnonmodal/ent:$002f$002fSD_ILS$002f0$002fSD_ILS:918804/ada here, ''Studies in Contemporary Jewry'' - https://pure.royalholloway.ac.uk/portal/en/publications/review-of-alan-s-rosenbaum-ed-is-the-holocaust-unique(4df21627-9748-49da-993c-f4ed1a7ff332).html here, so to me this is a '''keep''' as meeting
