Even when the technical problems involved in preserving digital works are relatively straightforward, libraries and publishers (whichever is doing the direct provision) have to deal with the fact that digital works require active effort on the part of provisioners in a way that is quite different from print. The Founding Fathers Papers and Founding Documents published by Rotunda provide good examples here. The papers are in XML, which will last a while and which will surely have a good migration path in the future, so the issue I have raised above is relatively unimportant. But no matter how stable the format, it costs money—power, hardware replacement, staffing the help desk—to make the works accessible every day. There is nothing very fancy about this—it’s actually analogous (if I may use that word) to the cost associated with keeping books on a shelf. But, unlike the cost of keeping books on a shelf, there is a continuous set of production activities and associated outlays of money that can be attributed to each digital publication. When a major research library “purchases” the electronic version of George Washington’s papers, it shells out several thousand dollars and it commits to paying an annual maintenance fee to cover operational costs and improvements.
One could arrange things differently, and make the publisher liable for the annual maintenance (in which case the one-time purchase cost would necessarily be much higher) but the simple fact that the electronic resource requires ongoing annual (actually, daily and hourly) cash outlay in order to be usable means the library/publisher nexus faces a set of problems that did not exist in the print age. These problems derive much more from changes in the ways libraries and publishers do business than from increases in the cost of doing business.
Note that in the journal world we have made the adjustment to ongoing annual cost by folding those costs into annual subscriptions. This was facilitated, I suspect, by the fact that serials have always been paid for on a subscription basis. The radical change that has taken place in the digital environment is that electronic versions of serials—including the backfiles in most cases—are now hosted on the publishers’ servers. Somehow librarians allowed the associated loss of control over the scholarly record to happen without all that much fuss, perhaps because there was no immediate effect on cash flow (the annual subscription model was already in place) and perhaps because the reliability of JSTOR and the development of Portico, LOCKSS and CLOCKSS give some confidence that the journal-based scholarly record will continue to be available. Academic libraries rail against the cost of electronic journals, and rightly so. But it is principally cost, and not either the frequency of payment (annual subscriptions are fine, they are just too pricey) or the loss of physical control that causes most of the wailing and gnashing of teeth.
Libraries are much less comfortable about annual fees to maintain electronic books—that is, to maintain scholarly works with content that is at least reasonably stable. From an economic point of view, this aversion makes little sense, because ongoing maintenance is every bit as important and as costly for print books as for electronic books. When a research library acquires a print book, it acquires the responsibility to care for it and make the content available indefinitely. Preservation and access are bundled into one technology and there is no practical way to separate them. But the cost of future access to the print resource is large—for conventional patterns of use and storage it is of the same order of magnitude as the cost of the book itself. Space has to be maintained and eventually replaced, buildings have to be heated and cooled, books are shelved, re-shelved, bound, etc.
The lifetime cost of preserving an electronic record with equivalent content to a print book is much less. The electronic version is cheaper to access and “re-shelve,” takes up much less space, no more power (servers are expensive to run, but heating and cooling large buildings is even more expensive). But the time pattern of outlays to support the housing of printed books is episodic, the annual costs are folded into the general cost of running the library, and, perhaps most important, these costs are not new—libraries have learned to absorb them. Although librarians and provosts pay attention to the cost of housing their collections, they tend to view new print acquisitions as assets rather than liabilities, and there is rarely explicit consideration of the ongoing stream of future expenditures that come with a new print book. An electronic book, on the other hand, makes those future costs immediately visible, and thus looks relatively more expensive even though it is actually cheaper. Kaiserlian’s observation that someone has to be concerned about the implications of perpetual stewardship is just as true for print as for electronic resources. The difference is that with print “someone” is always the library, and the implications of perpetual stewardship, however financially unpleasant, are familiar and are already, at least implicitly, in the budget.
