16CASLIN 2009 Citation data imports to Zotero A sample set of citation data from E-LIS eprint archive (110 records; BibTeX to Zotero) and from CERN Document Server (80 records; MODS to Zotero) gathered A sample set of citation data from E-LIS eprint archive (110 records; BibTeX to Zotero) and from CERN Document Server (80 records; MODS to Zotero) gathered At first sight these steps proceeded without any significant problems At first sight these steps proceeded without any significant problems Minor problems ocurred, e.g. viewing a record representing a document in Greek with characters from Greek alphabet Minor problems ocurred, e.g. viewing a record representing a document in Greek with characters from Greek alphabet

17CASLIN 2009 Citation data exports from Zotero Both data sets exported from Zotero in RIS format and imported to Connotea Both data sets exported from Zotero in RIS format and imported to Connotea As in the previous case, in general the import was successful but problems ocurred anyway As in the previous case, in general the import was successful but problems ocurred anyway Connotea informs the user about changes being made during import Connotea informs the user about changes being made during import

18CASLIN 2009 Citation data export from Connotea Export to BibTeX format Export to BibTeX format Comparison of original BibTeX files with these new ones (after two conversions took place) Comparison of original BibTeX files with these new ones (after two conversions took place) The files were significantly different: The files were significantly different: The Connotea export file did not contain abstract, other data (volume, number, pages, journal) were also lost The Connotea export file did not contain abstract, other data (volume, number, pages, journal) were also lost Author, title, year, keywords and URL were still present Author, title, year, keywords and URL were still present

19CASLIN 2009 Data loss – something to think about? Yes, certainly! Yes, certainly!

20CASLIN 2009 Discussion and conclusions A survey of institutional repositories has shown that not all repositories offer satisfactory citation data export options A survey of institutional repositories has shown that not all repositories offer satisfactory citation data export options Experiments leading to rather interesting results – at first sight everything is perfect, at second sight it becomes apparent that transformations lead to data (information) loss Experiments leading to rather interesting results – at first sight everything is perfect, at second sight it becomes apparent that transformations lead to data (information) loss Citation export capabilities as one of selection criteria for institutional repository software?
