Certain e-journals may likely only be viewed from the reading room because anything else might undermine the publisher's business model, and that is not the purpose of a legal deposit. |
Keeping the bits is not enough - you need to be able to recreate from them something that readers in decades and centuries to come will be able to use. |

The purists seem to think file emulation is the way to go, but it seems very complicated. We prefer to put our efforts into data migration - it is something we can do here and now. |
We acknowledge the considerable work that has to be undertaken by publishers to make the transition to a new structure for their electronic journal content. However, by supporting a common structure for e-journal content we have established a shared international context in which such migration can now proceed. |
We cannot afford to lose anything, and the probability of that happening with four copies is minute. |
