No need to print off documents and most patrons love getting them at their desktops. We have about one dozen patrons who still prefer to have paper copies. Our Systems staff person indicates that it should take about 2 hours to set up Prospero on a server and transferring all the necessary files. It takes about 1 hour to get going on the ILL side. Our students are the primary processors of Prospero documents and it takes a half hour to teach them how to Prospero documents.
Successful implementation seems to depend on how much IT support the librarian has.
Patrons ask about fixing the page orientation but otherwise have had no problems opening documents.
