To remedy this I've redone the site using frames. The right-hand frame displays the site's content, including a list of topics among other things. When the reader clicks on a topic, the left-hand frame displays the full names of all the individuals whose works I've quoted for that topic. When the reader clicks on the individual's full name, a page of quotations drawn from that individual's works appears in the content-frame to the right. To bring up the list of topics again, click on the first link in the menu on the left which says, Select a new topic.
Alternatively, the reader can examine all the quotations available at the site which were drawn from the works of a single individual. To do this, select the name of the individual who interests you from Mystics, theologians and scriptures. A list of quotations from this individual will appear in the menu to the left. To read quotations drawn from another indivdiual, click on the first link in the menu on the left which says, Select a new mystic.
All of the links which appear at the bottom of each page of quotations are nested in self-explanatory sentences.
A non-frames based version of the site automatically becomes available for those individuals who are using web browsers which don't display frames. I've browsed the site using Lynx without difficulty.
Three directories were previously devoted to the writings of Rumi; these have since been collapsed to a single directory. Similarly two directories previously devoted to Symeon the New Theologian have also been collapsed to a single directory. And the two directories dedicated to the Philokalia are now a single directory.
I removed Buber and Kaplan from the Jewish category, since I only had a single quotation per author.
