> You're arguing that since encyclopedias change their content, the Library of Congress should be allowed to change the content of the materials in its stacks.

As an end user of Wikipedia there are occasions where content has been scrubbed and/or edits hidden. Admins can see some of those, but end users cannot (with various justifications, some excellent/reasonable and some.. nebulous). That's all I'm saying, nothing about Congress or such other nonsense. It seems like an occasion of the pot calling the kettle names from this side of the fence.
