Thompson ISI Citation Information: a closer look at the math Impact Factor 2006 = 2006 citations (in ISI journals) to GENETICS’ articles published in 2004, 2005 number of GENETICS’ articles published in 2004 + 2005 4543 citations to recent articles 1071 total number of recent articles Impact Factor = 4.242 2006 citations (in all ISI journals) to GENETICS’ articles1 in 2005: 1981 published in 2004: 2562 total: 4543 GENETICS number of articles2 published in 2005: 548 in 2004: 523 total: 1071 Immediacy Index: .919 2006 cites to GENETICS’ articles published in 2006=558 558/607=.919 divided by Number of GENETICS’ articles published in 2006=607 Immediacy Index is the average number of times an article is cited in the same year it is published. Useful for comparing journals focused on “hot” research and fast publication. Cited Half-Life: 8.6 Cited Half-Life is the median age of articles cited in the current (2006) JCR year. Total Cites (of GENETICS’ articles in journals during 2006): 34,657 Number of times GENETICS’ articles are cited in ISI-indexed journals during 2006.
Table 1: GENETICS’ 2006 ISI Calculations
1 Articles in the IF numerator refer to source and non-source material in a journal that includes investigations, notes, letters to the editor, review articles, mini-review articles, proceedings, front matter/other items (news material, commentaries, editorials, book reviews). 2 Articles in the IF denominator refers to source items only – investigations, notes, letters to the editor.

Table 4: Excerpt from table showing, in 2006, journals citing articles published in GENETICS
Journal Citing Half-Life The citing half-life for the journal is the median age of the articles the journal cited in the current JCR year. Half of the citations in the journal are to articles published within the citing half-life. Citing Half-Life: 6.8 years
Table 5 shows the citations from the journal by the cumulative percent of 2006 cites to articles published in the following cited years. Clearly, the vast majority of cites from articles published in 2006 were to articles published in journals prior to 1996.

Table 6: Excerpt from table showing, in 2006, journals that were cited by articles published in GENETICS
Eigenfactor An Eigenfactor (EF) is a measure of overall value provided by journal articles published in a given year. With an Eigenfactor of .16, GENETICS ranked 6/298 in Eigenfactor’s Genetics and Heredity Field.3 The 2005 data ranks GENETICS 93/6327 of all journals classified. In terms of Eigenfactor rankings of all journals, the top three overall journals are Nature (EF 2.23), Science (2.13), Journal of Biological Chemistry (2.04), and PNAS (1.94). Interestingly, because EigenFactor adjusts for citation patters across disciplines, many influential journals (while not recognized by Impact Factor) are ranked highly according to EigenFactor. Nature, Science, and PNAS are classified in the Multi-disciplinary Sciences Field, and are not included in Table 7 (below). Article Influence (AI) is a measure of a journal’s prestige based on per article citations and comparable to (and typically correlates with) ISI Impact Factor. So, as indicated in the GENEtics print article, with a 2004 AI of 2.61, the average paper in GENETICS is 2.61 times are influential as the average article in the scientific literature indexed by Thomson’s ISI. Recent data indicates that, in 2005, our AI is 2.43. Table 7 shows the top-60 journal rankings in the Molecular and Cell Biology Category, in which GENETICS is listed (in EigenFactor) with a ranking of 41/506. While JBC’s ISI impact factor is a modest 5.808 – which puts it at 39/262 ISI-indexed journals in Biochemistry & Molecular Biology category – its EigenFactor ranking #1/506-journal Molecular & Cell Biology category – twice that of the next highest journal.

Bergstrom-McAfee Pricing For each journal in the index, the site provides information on price per article and price per citation, based on institutional pricing and information from ISI. The overall value of a journal is calculated by comparing the composite price index to the median for non-profit journals in the same subject. Each journal is given an overall value code – by color – green (very good), yellow (low value), red (very low value). Overall, Biology journals earning a: green/very good: 389 titles with Relative Cost Index <1.1 yellow/low: 294 titles with Relative Cost Index between 1.1 and 1.5 red/very low: 509 titles with a Relative Cost Index >1.5 GENETICS’ relative cost index of .22 earns it the highest category of cost-effectiveness (marked as “green” in the pricing index). Other Bergstrom-McAfee Pricing indices for GENETICS are: Price per article: $1.75 Price per citation: 0.51 Composite Price Index: 0.95 Relative Cost Index 0.22 The data for profit + non-profit 1191 Biology journals is: Mean Journal Price: $1,210.41 Median Journal Price: $756.00 Mean number of annual articles: 119.84 Median number of annual articles: 69.50 Mean number of citations: 319.57 Median number of citations: 88.30 Mean Price per article: $14.71 Median Price per article: $10.32 Mean Price per citation: $29.77 Median Price per citation: $8.09 Mean Composite Price Index: 15.06 Median Composite Price Index: 9.97 To look up cost information on GENETICS and other journals, see the beta version, freely available at http://www.journalprices.com. The site includes current data in Microsoft Excel,

allowing for easy sorting of all journals. Particularly interesting is the summary information – comparing price and cost data for profit and non-profit journals across all disciplines.
