Analytical index in epub books
 

Hello guys.

Anyone knows a way of "easily" adding an analytical index to an epub? That is, an index that lists for example the names of all the people it mentioned, and links them to each occurrence of that name. Of course one can use the "search" feature of the reader/SW, but a clickable index is a nice plus.

The thing to do is look for each word and insert an anchor with an ID, such as

which would require something like this in the index
The IDs have to differ if they are in the same html file, otherwise it is not necessary.

Of course this is next to impossible to do manually on a book of normal length.

So, yeah, is there a way to do it automatically, or anyway without so much effort? I think there might be one, because some epubs do have this feature. Maybe some scripting? From the vague notions I got of javascript I feel it might help, but I got no idea how.

Thanks :)

EDIT I found this question, which might get me a bit closer to the solution, except I don't have sublimetext (only calibre and N++)

Sigil has an automatic index feature:

1. Select Tools > Index > Index Editor.
2. Click Add Entry, enter a name and then click Save and Close.
(You can also paste a line-break separated list of names from the clipboard.)
3. Select Tools > Index > Create Index.

For more information on advanced Sigil indexing features see the Indexes help topic.

woa, cool. Good think I hadn't set up to create one manually.
