A problem can be seen just by looking at some of the group sizes. There is a persistence of 'invisible users' amongst the HEIRNET user community. 'Other', Personal Researchers, and 'Unknown' could encompass a large variety of users and together they comprised over a third of all the surveys returned. These three groups are over and above the truly unknown and invisible users who chose not to answer the survey at all! The 'Other' group turned out to be a discouragingly large number of respondents, and it is essential that its members be better identified to ensure that HEIRs properly understand the range of audience they have for their resource. The patterns of the 'other' group closely resemble that of both 'local government official' and 'museum professional', suggesting a kinship in some way. 'Other' claim jobs are a major reason for them to visit HEIRs, which means that they consider themselves to be employable within the sector, which narrows down slightly what their professions could be and emphasizes that this group is likely interested and active within the community, and not one-off users.
Some groups, like 6th Form College or High School students, Museum Professionals, Life Long Learners, and Non-vocational Archaeologists had very small user populations in this survey. Which could suggest either small participation overall in the community, or that the survey was not located at appropriate sites to reach a larger audience of these user groups (i.e. MLA website in order to survey more Museum Professionals).
