Inside Personalized Advertising, Printing Presses Were Good For The Economy, Digital Access, and Ebooks in Libraries

  1. Web-Scale User Modeling for Targeting (Yahoo! Research, PDF) — research paper that shows how online advertisers build profiles of us and what matters (e.g., ads we buy from are more important than those we simply click on). Our recent surfing patterns are more relevant than historical ones, which is another indication that value of data analytics increases the closer to real-time it happens. (via Greg Linden)
  2. Information Technology and Economic Change — research showing that cities which adopted the printing press no prior growth advantage, but subsequently grew far faster than similar cities without printing presses. [...] The second factor behind the localisation of spillovers is intriguing given contemporary questions about the impact of information technology. The printing press made it cheaper to transmit ideas over distance, but it also fostered important face-to-face interactions. The printer’s workshop brought scholars, merchants, craftsmen, and mechanics together for the first time in a commercial environment, eroding a pre-existing “town and gown” divide.
  3. They Just Don’t Get It (Cameron Neylon) — curating access to a digital collection does not scale.
  4. Should Libraries Get Out of the Ebook Business? — provocative thought: the ebook industry is nascent, a small number of patrons have ereaders, the technical pain of DRM and incompatible formats makes for disproportionate support costs, and there are already plenty of worthy things libraries should be doing. I only wonder how quickly the dynamics change: a minority may have dedicated ereaders but a large number have smartphones and are reading on them already.
