Fortunately for us in a Web-based course, all the components are present and can be referenced as needed. I have organized the course as a series of modules. I have ordered the modules with a purpose. They are ordered with a mind to the information needed to understand what follows, assuming that the student has no prior knowledge of the subject matter. With this in mind, we will not look at catalogs as such until we have explored how Web catalogs and indexes are created.
Some indexing is automatic, some in manual.
And so on. At times, I provide links to other site pages to support arguements and to avoid redundancy. A couple of things to remember. First, this is a survey course. In a scant semester it is not possible to go into full and technical detail about everything.
