I fully agree with this. In general, lock-in is pervasive in the use of any information product. It even appears in the informational use of non-information products. Example: a supermarket provides you with your groceries. It's not an information product. Yet, you will prefer to use a supermarket that you are familiar with because you know where to find what you want. Lock-in reduces competitive forces. An important advantage of open-source solutions is that they reduce lock-in. They can't eliminate it because it is generic to the nature of information. > As a general statement -- and I know that this battle has been bitterly > fought in the ILS space -- It is not bitterly fought elsewhere because people just don't think this far. They think, say, "oh Google gives me such a great infrastructure for my email. And I don't care about the spying thrown in for good measure. So let me go for it." But twenty years from now will you have an archive of your mails? If you change providers, do you migrate the email archives? These are important questions to ask. I have not used Google mail, neither have I used libguides, so I have no idea how easy or how hard it is to migrate. But it is important to keep this is in mind when choosing between informational products. > I believe that *all* library software services, whether based on > F/LOSS software or proprietary software, should provide a way for > the library to obtain a full dump of their data, in an accessible > format, at no additional charge.
