My name is Melanie and I am working in a small scientific library. There are a lot of free resources like open access journals or PhD thesis on the internet. Unfortunately they are not collected in one single catalogue and they might change location and/or the restriction of accessibility. So, how can we, the librarians, first of all find the different resources and then keep the overview of all, their location and their change of accessibility to provide the best service for our customers? Is there a way?
