An explanation of the two terms.
You are considered an external user if you are using the Digital Library from outside the Wageningen University & Research (WUR) network and you are not logged in to My Library. External users can't use the personalized services and have no access to licensed resources.
You are considered a guest user if you are logged in to My Library from outside the WUR network, but not recognized as a WUR employee or student. This will happen if you don't use your WUR e-mail address when registering for My Library.
New since March 2018: In order to (continue to) make use of the online services of WUR Library, you have to create a new guest account with OneGini.
Guest users can use most personalized services, but have no access to licensed resources.
