- Abstract
- We determine analytically the modulus of the second eigenvalue for the web hyperlink matrix used by Google for computing PageRank. Specifically, we prove the following statement: "For any matrix A=(cP + (1-c)E)**T, where P is an nxn row-stochasticmatrix, E is a nonnegative nxn rank-one row-stochastic matrix, and 0<=c<=1, the second eigenvalue of A has modulus Betrag (Lambda_sub2)<=c. Furthermore, if P has at least two irreducible closed subsets, the second eigenvalue Lambda_sub2 = c." This statement has implications for the convergence rate of the standard PageRank algorithm as the web scales, for the stability of PageRank to perturbations to the link structure of the web, for the detection of Google spammers, and for the design of algorithms to speed up PageRank.

- Abstract
- It may be jumping the gun a bit to review this publication before it is actually published, but we are nothing if not current here at Current Cites, so we will do it anyway (so sue us!). This publication-in-process is a joint effort of the Visual Resources Association and the Digital Library Federation. It aims to "provide guidelines for selecting, ordering, and formatting data used to populate catalog records" relating to cultural works. Although this work is far from finished (Chapters 1, 2, 7, and 9 are available, as well as front and back matter), the authors are making it available so pratictioners can use it and respond with information about how it can be improved to better aid their work. A stated goal is to publish it in print at some point in the future. Besides garnering support from the organizations named above as well as the Getty, the Mellon Foundation and others, the effort is being guided by experienced professionals at the top of their field. Get the point? If you're involved with creating metadata relating to any type of cultural object and/or images of such, this will need to be either on your bookshelf, or bookmarked in your browser, or both

- Abstract
- This report constitutes Phase I of a two-part study; a Phase II report will discuss subject cataloging. Phase I is concerned with the materials of a library as individual records (or documents) and as representations of certain works by certain authors--that is, with descriptive, or bibliographic, cataloging. Discussed in the report are (1) the history, role, function, and oblectives .of the author-and-title catalog; (2) problems and principles of descriptive catalogng, including the use and function of "main entry, the principle of authorship, and the process and problems of cataloging print and nonprint materials; (3) organization of the catalog; and (4) potentialities of automation. The considerations inherent in bibliographic cataloging, such as the distinction between the "book" and the "work," are said to be so elemental that they are essential not only to the effective control of library's materials but also to that of the information contained in the materials. Because of the special concern with information, the author includes a discussion of the "Bibliographic Dimensions of Information Control," 'prepared in collaboration with Robert M. Hayes, which also appears in "American Documentation," VOl.201 July 1969, p. 247-252.
