Hi all, Running Koha 3.20.02 on Ubuntu 14.04 LTS with Apache 2.4.7. I had a question about the authentication of electronic resource links in Koha. I'd like to explore a method of managing access to links to e-resources (856 fields) that would (1) prevent an anonymous user from navigating to the full-text of an e-resource via the 856 link; and (2) to show an 856 link to the full-text of an e-resource to authenticated users. I am thinking here of how universities and colleges manage their e-resources (i.e., allow registered students access to e-content but denying unauthorized access from unofficial users). The problem is that I've never talked with anyone who could explain how this is done generally. I'm sure it varies across institutions. So, can Koha (presumably with server-side software) do this, and how can it be done? Is this what CAS or SIP2 is for? Hope this is clear. Happy to provide more info. This is not my area, but I'd like to explore further. Feel free to point me to info resources on this too. Many thanks! Craig Butosi, MA, MLIS, B Mus (Hons.)
