DDQ Volume 5, Number 1:                                                                                                        1Q2006

This number asks "Why So Slow towards Practical Preservation?" and suggests answers that are admittedly incomplete, and are perhaps also controversial.  DDQ offers to publish brief dissents with its opinions.

It also contains a dozen short reports on preservation and innovation announcements of more than average interest, starting with several European items.  Its "Home Computing" section suggests several free or inexpensive utility programs that appeal to me.
