This interesting site is a "database of potential suppliers of ICT and digitisation resources for the cultural and heritage sector" in the UK. It is maintained by the Museums, Libraries and Archives North East (MLA North East), the regional strategic development body for Museums, Libraries and Archives in the North East of England.
There are far too few sites that provide information on hardware, service providers, and other aspects of digitization. Perhaps someone should take MLA's lead and do such a site for other geographic regions.
