- Abstract
- The fields of informetrics and scientometrics have suffered from the lack of a powerful test to detect the differences between two samples. We show that the Mann-Whitney test is a good test an the publication productivity of journals and of authors. Its main limitation is a lack of Power on small samples that have small differences. This is not the fault of the test, but rather reflects the fact that small, similar samples have little to distinguish between them.

- Abstract
- In addition to stipulating economic rights, the copyright laws of most nations grant authors a series of "moral rights." The development of digital information and the new possibilities for information processing and transmission have given added significance to moral rights. This article briefly explains the content and characteristics of moral rights, and assesses the most important aspects of legislation in this area. The basic problems of the digital environment with respect to moral rights are discussed, and some suggestions are made for the international harmonization of rules controlling these rights

- Abstract
- University Library at Indiana University-Purdue University Indianapolis (IUPUI) acquired a large and unique collection of foundation annual reports. It was decided that cataloging them as serials, with the attendant problems of successive entry maintenance and access, was not acceptable. The reports for each foundation were treated as a collection with a unifying, made-up main title and updateable holdings (245 $f). The concept of main entry was retained, but the actual entry changes when the foundation name changes. The authors conclude with a call to make rules 21.3B1 and 21.2C1 optional.

- Abstract
- The widely used Web search engines index and recommend individual Web pages in response to a few keywords queries to assist users in locating relevant documents. However, the Web search engines give different users the same answer set, although the users may have different preferences. A personalized Web search would carry out the search for each user according to his or her preferences. To conduct the personalized Web search, the authors provide a novel approach to model the user profile with a self-organizing map (SOM). Their results indicate that SOM is capable of helping the user to find the related category for each query used in the Web search to make a personalized Web search effective.

- Abstract
- This article examines the question, "What differences do libraries and librarians make?" primarily from the perspective of geographical communities. The article first states the reasons why this is an essential research question and describes the contributions of current public library planning tools to the determination of impact. It then takes a broad look at the framework that is essential for the intellectual development of this topic and the ability to answer the question, including methodological approaches and theoretical frameworks that will be discussed throughout. While the authors pose this research problem as an evaluation question, this article examines contributions of research in several areas--particularly professional practice, especially reference research that has been informed by qualitative methods--to its solution. Finally, the authors examine approaches to studying context as a framework for determining the impacts of library services and include a brief presentation of findings from a recent study of "How Libraries and Librarians Help: Context-Centered Methods for Evaluating Public Library Efforts at Bridging the Digital Divide and Building Community," funded by the Institute of Museums and Library Services (IMLS).

- Abstract
- Previously, a new method for measuring scientific productivity was demonstrated for authors in mathematical logic and some subareas of 19th-century physics. The purpose of this article is to apply this new method to other fields to support its general applicability. We show that the method yields the same results for modern physicists, biologists, psychologists, inventors, and composers. That is, each individual's production is constant over time, and the time-period fluctuations follow the Poisson distribution. However, the productivity (e.g., papers per year) varies widely across individuals. We show that the distribution of productivity does not follow the normal (i.e., bell curve) distribution, but rather follows the exponential distribution. Thus, most authors produce at the lowest rate and very few authors produce at the higher rates. We also show that the career duration of individuals follows the exponential distribution. Thus, most authors have a very short career and very few have a long career. The principal advantage of the new method is that the detail structure of author productivity can be examined, such as trends, etc. Another advantage is that information science studies have guidance for the length of time interval being examined and estimating when an author's entire body of work has been recorded.

- Abstract
- Normalization rules are essential for interoperability between bibliographic systems. In the process of working with Name Authority Cooperative Program (NACO) authority files to match records with Functional Requirements for Bibliographic Records (FRBR) and developing the Faceted Application of Subject Terminology (FAST) subject heading schema, the authors found inconsistencies in independently created NACO normalization implementations. Investigating these, the authors found ambiguities in the NACO standard that need resolution, and came to conclusions on how the procedure could be simplified with little impact on matching headings. To encourage others to test their software for compliance with the current rules, the authors have established a Web site that has test files and interactive services showing their current implementation.

- Abstract
- The outputs of several information filtering (IF) systems can be combined to improve filtering performance. In this article the authors propose and explore a framework based on the so-called information structure (IS) model, which is frequently used in Information Economics, for combining the output of multiple IF systems according to each user's preferences (profile). The combination seeks to maximize the expected payoff to that user. The authors show analytically that the proposed framework increases users expected payoff from the combined filtering output for any user preferences. An experiment using the TREC-6 test collection confirms the theoretical findings.
