Nisenholtz admits that paid archives on NYTimes.com only brings in a percentage in "the low single digits" of overall online revenues, and Borrell Associates estimates that paid archives account for less than 5 percent of online revenues for newspaper sites.
But the sale of archives to LexisNexis, Factiva, ProQuest and others is a "significantly higher number" for NYTimes.com, according to Nisenholtz. While there's no stipulation in its database contracts for NYTD to keep archives behind a wall, Nisenholtz realizes that making archives free online would erode their value in other places."
