In dealing with electronic information resources, what librarians bring to the table is evaluative guidance. On many library Web sites, the user is hard-pressed to identify the staff, whose names, if they're there, are five levels down. The human factor is still important. Co-opt existing technologies that haven't been used in libraries, and take advantage of cooperative efforts in information access.
Libraries can afford less and less wasteful inefficiency and duplication of effort.
Libraries are going to have an increasing interest in verifying that you are who you say you are, you do have the right to access this resource, and the resources you are receiving are authentic. Often just as important to libraries as emerging technologies are submerging technologies.
