   Remote Patron Access:
     No-Tech Versus High-Tech
The problem:
It’s not who you are --
it’s where your are.
How do you choose a
remote authentication
solution?
How do you choose a
remote authentication
solution?
   Scalability
     How  well does it work as the number of
      patrons and/or resources grow?
How do you choose a
remote authentication
solution?
   Cost
     Some  are free. Others require software
      and hardware that can cost a lot of
      money.
How do you choose a
remote authentication
solution?
   Ease of use
     Isit easy for patrons to use?
     How much time will you spend helping
      remote patrons troubleshoot their access
      problems?
How do you choose a
remote authentication
solution?
   Security
     How  well does the solution protect your
      database from unauthorized use?

   Library Technical Expertise
     Doesyour solution require advanced
      computer skills to install and maintain?

The No-Tech Solution
   Give each patron the database
    password.
      Scalability?

      Cost?

      Ease of use?

      Security?

      Library Technical Expertise?
High-Tech Solution I
   Use a proxy server.
     How does a proxy server work?

        A proxy server is a server installed

         as part of the library network. Library
         patrons connect to remote
         databases through the proxy server.
         The remote database only sees the
         IP of the proxy server, so the patron
         is allowed access.

     Cost?
     Ease of use?
     Security?
     Library Technical Expertise?
High-Tech Solution II
   Use Z39.50
     The Z39.50 standard provides a way

      for the library to transmit a username
      and password to a remote database.

     Cost?
     Ease of use?
     Security?
     Library Technical Expertise?
High-Tech Solution III
     Referrer URL
        Each time you go to a new web

         page, the URL of the previous page
         is transmitted. So ...
            Put a page on the library site with

             links to databases. Limit access
             to the page to library patrons.
            The database allows access

             when the referring page is the
             page on the library’s web site.

     Cost?

     Security?
     Library Technical Expertise?
High-Tech Solution IV
     Obvia Remote Database Access
      (RDA) Service
        Claims to be a “turnkey solution”

         running on a server at the library or
         at Obvia’s site.
            Library is responsible for entering

             patron data. Obvia handles the
             connection to vendor databases.
            More info: www.obvia.com
In conclusion ...
     There is no single best solution.
     If possible, make remote access to
      library resources part of your
      institution’s overall effort to make
      services available to remote users.
