1 Appendix A Comparison of Research Area (SU) categories and Web of Science Categories (WC) The Research Areas (SU s) considered in this study correspond with the one hundred thirty- six Research Areas included in records in the Web of Science in June and July 2011 and not identified as one of the fourteen Research Areas in the Arts and Humanities research domain (as identified in Thomson Reuters support materials). The Arts & Humanities were not included in the analysis because these fields are believed to differ in terms of publication patterns, in the use of language related to synthesis and in approaches to synthesizing research. The Web of Science Categories (WC s) correspond with those available in The 2010 rather than 2011 categories were used because cross- category citation data is readily available for this year (Leydesdorff, et al., 2013). The Audiology Speech Language Pathology category was added to the Journal Citation Reports in 2011, and therefore is not included in the cross- citation data. This set includes records for Arts and Humanities WCs to the extent that they are indexed in the S/SCI. The 123,881 records that comprise the dataset for this study correspond with 176,128 Research Area (SU)- record, and 186,151 Web of Science Category (WC) instances. Therefore, the dataset records were assigned approximately Research Areas, and WCs. As a result, the category counts inflate the apparent total number of records by about 42% when Research Areas are used; and about 50% when WCs are used. The average number of SU and WC cross- categorizations

2 for the study data set is higher than the average number of cross- categorizations for records of all items published 1972 to Across the four decades, 41,268,729 records were found with publication year searches. About 53,542,935 Research Areas are indicated across the set, which corresponds to an average of Research Areas per record. About 56,847,805 WCs are recorded across the set, about categories per record for the categories considered in the analysis. Since the figures across the database for includes all records, and is not stratified to reflect the relative number of records per year in the data set used for this study; it s possible that some other factor accounts for the difference. For example, it is possible that earlier publications could be less likely to be cross- classified in several categories. Evidence from other studies suggests that this could be the case (Rafols & Leydesdorff, 2009; Rinia, Van Leeuwen, Bruins, Van Vuren, & Van Raan, 2002), which could be explainable if, for example, titles added to the S/SCI in more recently more likely to be multiply categorized than were ones added less recently. In order to identify the relationship between the two category systems, a search for each WC, limited to documents published between 1972 and 2011 was performed. WCs were matched with SUs that included 100% of the SC publications. These searches indicate that approximately 110 Research Area and WC categories appear to be approximately equivalent based on record counts and title similarity (Table A1); fifteen SUs aggregate two WCs (Table A2); three SUs aggregate three WCs {Table A2); two aggregate four WCs (Table A3), and eight SUs aggregate five or more WCs (Table A3). 2

These categories were not uniformly used across analyses in this study. Therefore, the data is not included here. A large difference in the total number of documents for Hematology was observed between September 2012 and February It s possible that this difference is due to changes in the database. February 2013 data indicates that the Hematology WC and SU include the same documents. This similarity is not evident based on the data presented here and used in this study.
