I’ve finally got round to linking in the footnotes in the text of The Serpent in the Shrine. I put the notes in a table in the back-end database, thinking that I could then call them up using Ajax technology to insert them in the mouseover tooltip. But I changed my mind deciding instead to hardcode them into the title attributes of the relevant anchor tags on the principle that simple is best. So that’s what I’ve done. I have, however, added custom-built tooltips using JavaScript to hold the sometimes substantial footnote content.
