In general you would expect older articles to have been cited more frequently. This is the only article, so far, to have cited the 1995 article in the Journal of the Association for Learning Technology . Note that this journal is not even indexed by BIDS ISI . Citation searching allows us to look forward in time from an article and see who is referring to that work. It is a useful way of finding out about new authors in a field.
People often repeat searches that others have done in the past.
Usually there is no way to re-use these searches and so save time and effort. Whenever items have been organised into categories similar things are found next to each other. This is most obvious in a Library or Bookshop, where books on the same topic or by the same author are on the same shelf. In Lancaster Library the Classmark associated with each item allows you to look for things with the same, or a similar, Classmark. Hierarchical Indices on the Web, or a CD-ROM, also enable you to look for similar things.
