The idea of digital libraries is not new; but recent developments have
made the realisation of this idea more of a practical possibility tha
n ever before. In particular, the availability of tools for easy acces
s to information and for easy production of new information has encour
aged traditional publishers to make their information available in dig
ital networked form, but also made it possible for many individual aut
hors to directly publish their own information on the Internet, bypass
ing traditional publishers and established bibliographic systems. Mana
ging these new information resources is the task of Internet digital l
ibraries such as OMNI. A key issue is the need to signpost the quality
of information sources. A variety of ways of doing this are possible.
