Essentially the message here is that in v19, the functionality that is currently split across a web ILL interface (for ISO ILL), and a GUI client interface (for non-ISO ILL) is being brought together into a single GUI client interface (GUI ILL2). This single GUI will be available in v18, but v19 will only have this single GUI, with the old GUI and Web interfaces being deprecated.
This will bring the ILL GUI in line with the other GUI interfaces in Aleph.
I’m looking forward to having the new ILL GUI, but to be honest our ILL dept works fine at the moment, and we probably don’t have enough traffic to gain much from the ISO ILL functionality.
