Usability of Digital Libraries: Editorial

The issue of usability has concerned the Digital Libraries community, at least peripherally, over many years. There is, after all, little point in delivering sophisticated libraries with novel features if those systems are then ignored by the intended users because they are too difficult to use or do not offer the key features that users require. However, the challenge of how to deliver Digital Libraries that are truly useful and usable remains elusive, often given second place to solving novel technical challenges.
