Quick update to alert you that Springer have made our book Knowledge Cartography: Software Tools and Mapping Techniques available as an eBook for €25 🙂
You can view the Preface for free on the eBook page, but this has been online in full as HTML from the start.
Unfortunately Springer’s eBooks are priced at €25 per chapter, so that’s €425 (17 chapters at €25 a pop). I’ve asked previously about reduced whole-book pricing: They say they won’t do it. So it’s effectively 4 times the price if you want PDFs instead of print.
However, it’s nice to have the back matter as a free PDF (especially the index). And thanks for pointing to the HTML summaries.
