In this study, we use the fact that endogenous eyeblinks point to cognitive state in information processing, we examine how information processing by user is performed in each case and how different they are; 1) when referring to structured information by curation, 2) search engine result page and the individual page by accessing and referring to it as a starting point.

As a result, task as a whole, in any task, using curated information is performing higher order information processing. In addition, we analyze browsed page divided into the originating page (P1) and the individual page (P2). The results show that group they use curated information, in P1 and P2 of travel task and P1 of report task is performing higher order information processing.

Finally, this study demonstrates the usefulness of using eyeblinks as a quantitative method in information behavior analysis.

The ratio of printed books being converted to e-books is increasing every year. To measure the status of e-book conversion, we devised a method to acquire the bibliographic data of printed versions from the collection at the National Diet Library and compared it with the data provided by the main e-book platform, to calculate the e-book conversion ratio. We proposed the following hypotheses: 1) in recent years, the e-book conversion ratio has increased, 2) larger publishing companies with more publications have a higher e-book conversion ratio, 3) the e-books available on each platform overlap, 4) the e-book ratio of comic books is high, 5) the e-book ratio of academic books is high, and 6) the e-book ratio of novels is high. The e-book ratio in 2017 was 36.6%, and thus, it was estimated that there are now around 30,000 e-books. With the exception of 2) and 5) the findings supported the other hypotheses. In addition, the number of records of the National Diet Library Digital Collections was investigated from 1901 to 1980. It was noted that there was a blank period of e-books between the period around 1960 and 2000.
