New contextual pop-up help
I’m not really sure what to call this. Tool-tips? Hover help? Anyway, you should now notice something new if you hover your mouse cursor over any of the linked words in Diary entries. Here’s an example:

Most of these pop-up tips will only show the name of the person, place or thing mentioned, although even this is useful when Pepys isn’t very specific in the Diary entry itself. But of the 2,875 Encyclopedia topics, I’ve written short summaries for more then 500 of them — all those that have Wikipedia pages associated with them.
This leaves a lot of links without decent summaries and I’d love it if any of you felt like writing one or more. Just email me the text and the link it should be associated with (eg, http://www.pepysdiary.com/p/150.php). Summaries should be up to 60 words and summarise the person, place or thing in a way that will be useful for the life of the diary. Where possible I tended to focus particularly on information around the diary person, such as how a person faired upon the Restoration. Also, I’m not attached to any of the summaries I’ve written so far, so if you feel you can improve on any, do email your versions to me at the usual address!
These tips won’t show up if you read the diary by email, or RSS. There’s also a bug that means the tip won’t show up in Internet Explorer on Windows if its link is at the very left hand edge of the Diary entry. I’m not sure if I’ll be able to fix that.
I hope you find these useful!
