Despite the wide computerization of library catalogs, librarians tend to still be paper-based. They worry about email spam and viruses, so employ sophisticated systems that will quickly filter out messages from anyone they don’t know. For this reason attempts to reach libraries via email is futile. Instead, use postal mail, perhaps combining your efforts in a co-op mailing with other authors.
