Here's code I've had in my config for quite a while. It gets the logbook, and shows the most recent item, bound to "V" in the agenda. It also includes an aborted function to do more thorough parsing of the log items -- I abandoned that because it was too gross. I actually also have a library called org-log.el around here somewhere, but that does quantitative logging of values, which I don't think has enough general interest. But I'm attaching that, too, just in case. Anyway, I'd be happy to work on this. (defun org-get-log-list () "Return the entry's log items, or nil. The items are returned as a list of 'item elements."

Those ;; values can later be viewed as tables. Essentially this is a ;; generalization of org-clock, to allow logging of other values. ;; Like org-clock, it also includes a command to view logged data as ;; an Org table. ;; In terms of format, a logged value appears as an all-caps label, ;; followed by a colon, followed by the data itself, followed by a ;; semi-colon. For instance: ;; BP: 120/60; PULSE: 45; ;; The `org-log-buffer-setup-hook' is used to prompt the user for log ;; values to store. It does this by looking for a LOG_VALUES property ;; on the heading, which should be a space-separated list of all-caps ;; value labels. These labels can also contain information about the ;; units used for the value. Units are specified immediately after ;; the value label in square brackets, like so: ;; DISTANCE[mi] ;; This unit information will be automatically incorporated into ;; tables created to view logged data.
