TL;DR: The concept of utility time is introduced to measure the impact of the ADS/URANIA and the electronic astronomical library on astronomical research and it is found that in 2002 it amounted to the equivalent of 736 full-time researchers, or $250 million, or the astronomical research done in France.

Abstract: By combining data from the text, citation, and reference databases with data from the ADS readership logs we have been able to create Second Order Bibliometric Operators, a customizable class of collaborative filters which permits substantially improved accuracy in literature queries.
Using the ADS usage logs along with membership statistics from the International Astronomical Union and data on the population and gross domestic product (GDP) we develop an accurate model for world-wide basic research where the number of scientists in a country is proportional to the GDP of that country, and the amount of basic research done by a country is proportional to the number of scientists in that country times that country's per capita GDP.
We introduce the concept of utility time to measure the impact of the ADS/URANIA and the electronic astronomical library on astronomical research. We find that in 2002 it amounted to the equivalent of 736 FTE researchers, or $250 Million, or the astronomical research done in France.

A classification of mental models of undergraduates seeking information for a course essay in history and psychology: Preliminary investigations into aligning their mental models with online thesauri
TL;DR: In this paper, the authors report a field study which examined the mental models of 80 undergraduates seeking information for either a history or psychology course essay when they were in an early, exploration stage of researching their essay.

Upper tag ontology for integrating social tagging data
TL;DR: The Upper Tag Ontology (UTO) emphasizes the structure of tagging activities to facilitate modeling of tagging data and the integration of data from different bookmarking sites as well as the alignment of tagging ontologies.

Blind men and elephants: What do citation summaries tell us about a research article?
TL;DR: The study shows that citation summaries overlap to some extent with the Abstracts of the papers and that they also differ from them in that they focus on different aspects of these papers than do the abstracts.
The Access/Impact Problem and the Green and Gold Roads to Open Access: An Update

TL;DR: The research access/impact problem arises because journal articles are not accessible to all of their would-be users; hence, they are losing potential research impact as mentioned in this paper. The solution is to make all articles open access (OA, i.e., accessible online, free for all).

The Access/Impact Problem and the Green and Gold Roads to Open Access☆

TL;DR: To reach 100% OA, self-archiving needs to be mandated by researchers' employers and funders, as the UK and US have recently recommended, and universities need to implement that mandate.

The Matthew effect in science. The reward and communication systems of science are considered.
TL;DR: The psychosocial conditions and mechanisms underlying the Matthew effect are examined and a correlation between the redundancy function of multiple discoveries and the focalizing function of eminent men of science is found—a function which is reinforced by the great value these men place upon finding basic problems and by their self-assurance.
