Dear colleagues, In response to the recent update of the Web-of-Science interface (v5) of the Science Citation Index, I recompiled the following programs: 1. ISI.exe <http://www.leydesdorff.net/software/isi> for the organization of downloads into the structure of relational database management; 2. Instcoll.exe <http://www.leydesdorff.net/software/instcoll/index.htm> for the network analysis at the institutional level; 3. Intcoll.exe <http://www.leydesdorff.net/software/intcoll/index.htm> for the network analysis at the country level; 2. Cities1.exe <http://www.leydesdorff.net/maps> for the (Google) mapping of cities and networks (Leydesdorff & Persson, JASIST, 2010); 3. Inst1.exe <http://www.leydesdorff.net/maps> for the similar mapping at the institutional level. The latter two programs can also used for the mapping of excellence at the city or institutional level: http://www.leydesdorff.net/topcity (Bornmann & Leydesdorff (JASIST, 2011) and http://www.leydesdorff.net/mapping_excellence (Bornmann et al., JoI, 2011). The programs have been recompiled using Win32 software instead of the 16-bit Dos. Thus, one can run them under a 64-bits operating system. If you run the program from the C-prompt it either finishes or provides an informative error message. The fields containing information other than addresses were not changed. I therefore do not intend to recompile the other programs, but one should be aware that there can be incompatibilities between downloads in v4 or v5 in the address information.
