Ezproxy was designed to provide off-campus access to databases and other restricted electronic resources to which a library has subscribed from one supplier, and does it very well. We also use Ezproxy to provide free internet access on-campus to these resources which normally should bypass Ezproxy altogether and this works pretty well. The problem has occurred when we try to integrate Ezproxy into open access Web 2.0 resources like Libguides which link to many related resources. Ezproxy requires each service to be specified.
With Libguides this has become unmanageable on the student installed machines which use Webgate to authenticate. Each time Library IT fixes a problem another link is added that breaks, and as with all Web 2.0 environments users as well as Library staff will also be able to add links as comments etc. LibGuides links are also being added to Moodle and other services that we cannot control. We have discussed other options with ICTS such as using Internet Enabler instead of Webgate or firewall changes, but that creates worse problems for students
Libguides is openly available both on and off campus. Ezproxy has been added to Libguides only to try to pay for the internet charges. All students will be getting some free internet quota from the university which last year met the needs of 75% of the undergraduate students. Students are now used to paying for internet services and putting money on their Canterbury Card. Libguides will also work faster without Ezproxy.
We did not integrate AskLive into Ezproxy when we moved to Meebo for similar reasons, and have had no complaints.
The Library has had a policy of making our major electronic databases free to users, as is the print, by absorbing the internet costs. This is no longer technically possible to do reliably with our off campus web 2.0 applications on student workstations.
I will be recommending to LLT that from now on users will need to pay the internet charges for products such as Libguides, AskLive, other library catalogues and similar applications. Library databases will continue to go through Ezproxy.
I know some staff feel quite strongly about this. Comments most welcome, preferably before LLT. Cheers, Anne
