In that context, I would include standard reference works, full text electronic journal and magazine publishing, electronic technical reports and short reports, abstracting and indexing databases covering magazines and journals, electronic government documents, and general and some specific textual information. Book publishing is the same as always and there doesn't seem to be a movement to electronic. Direct user access to indexing databases has made the expertise of reference librarians in information retrievel more evident. Electronic journals are making the cost and expertise of editing more evident. Publishers stress that the editorial cost is a major portion of their cost of production.
Electronic journals have a licensing fee in addition to the print cost.
Web-only subs may cost a bit less but the annual price increase structure of scholarly journal publishing is killing the golden goose. Change will take time but indicators are that universities and scientists will introduce lower-cost electronic journals in competition with more expensive commercial journals. This may open up local editing work for those networked to universities and scientists. However it has never been easier to get work one in the academic library environment. Typically a library user comes in looking for a precise answer, a small amount of information on a topic, or a review of information on a topic.
