If you run a search in LexisNexis Academic and try to sort the results from newest to oldest, you’ll see that the results aren’t in the order that you requested (or any order). Sorting from oldest to newest seems to work, as does relevance sorting (as far as I can tell). According to a post today on ERIL-L mailing list, LexisNexis is aware of this problem and a fix for it may not come until May (ugh).
