“ What is done for names not of the surname, forenames type (all the "John de" and "John of" names, for example) was changed between the DNB Epitome and the later Concise version, which you may find in a library. You cannot rely implicitly on the Concise DNB for this issue, therefore, to predict the order in a bunch of medieval names, though in general it is a helpful reference. ”

“ Bisection method If you don't have a precise page number to aim at, you should establish a range, and then subdivide it (bisection method) . This normally is much quicker than using < and > in pagespace to move any distance. To set up the range, look in the volume ToC for articles preceding and following the one of interest. Where these are transclusions with the indented left margin, that margin shows djvu page numbers (DP) , and tells you where in pagespace that article sits. Where the transclusion is done by the #section method, you can edit the page to read off the page numbers also. ”

“ This may fail if no text has yet been created for the page, if the text is badly scanned, or because the name is too common and throws up too many hits. Navigational methods are more robust, if not offering a very rapid solution, and can also determine quite definitely if an article is for some reason not there under the expected name.
Indexation The first column shows the volume corresponding to a surname (or personal name for royalty, medieval people and some other cases) . ”
