I have always known how cumbersome it can be to get some electronic resources, but the flow chart from Rick Anderson at the University of Nevada, Reno Libraries really illustrates the many paths and decisions that e-resources can take.

It is no wonder that recently I have been seeing a sudden increase in electronic resources librarian positions in the job ads. As more and more things become available in different flavors, shapes, sizes, colors, it now takes a full time professional just to deal with all of it. I would venture to say that many libraries have "accidental" electronic resources librarians. Librarians who were techie types to start out with but weren't necessarily systems librarians. As the amount of available resources grew so did their electronic resources workload. Gradually they morphed from the reference librarian who did electronic resources to the electronic resources librarian who did reference. As these librarians leave to find new jobs the old library discovers they have a need for an electronic resources librarian.

Obviously the explosive growth in electronic resources can lead to a lot of new things, whether it is IP range problems, finding money to support the resources, or finding personnel to support the resources.
