Every afternoon after 3 P.M., it takes 40 seconds to pull up Google or CNN. Your staff has to wait until the next morning to send cataloging records to a remote branch. Video or audio downloads are out of the question. Your first response might be, “Buy more bandwidth!” and that’s not a bad idea at all, but you might not have enough money to buy more bandwidth. Moreover, some libraries are finding that patrons will fill up everything they’re given. Double your bandwidth, and a month later it’s slow again after 3 P.M.
In one sense, you already have an army of network monitors in your library. Every time something goes wrong, you probably get a few spontaneous alerts from patrons and colleagues. However, if you want preventive information and in-depth analysis of what’s happening on your network, you need network monitoring software.
Total cost of ownership, or TCO, is a business concept that’s been around for about 20 years now, but it’s an idea that librarians have understood informally for centuries. When a patron loses a book, most libraries charge more than the cover price of the book, because the cover price doesn’t include the cost of ordering, processing and cataloging the book. The staff time involved in getting that book into the system is part of the TCO of that book. If you look out even further, there are costs related to shelf space, repairs, circulation, reshelving it and deaccessioning.
