Graphical legal publishing history

Hats off to fellow law librarians Sarah Glassmeyer and Greg Lambert for making visual charts that graphically show the shrinking world of legal publishing, a topic that is of concern to all law librarians. First Sarah created a chart , linked from her blog, that gives a visual representation of some of the major mergers in the field. Then Greg Lambert, inspired by the idea, blogged about it and updated the chart to include more types of legal information companies and specifically the growth of Thomson Reuters. Greg also made his spreadsheet available on Google Docs so anyone interested can add information.
