The citation practices of academics and practioners who have published papers in the proceedings of a national computer conference are analyzed in order to measure how the two groups differ in their use of published information. The comparison is based upon types of documents cited, age of cited literature and core journals cited. The study found that both groups cited the same group of core journals and cited documents of approximately the same age. Both groups cited journals most frequently and when document types are ordered according to citation frequency, the rankings are identical. However, the actual citation frequencies by type of document are not the same and these differences are attributed to unequal levels of awareness and access to specific categories of documents.
