2  An increasing amount of students and scholars use web references as a prime source in their papers  The main concern : ◦ web references have a short lifespan  Web references disappear within two or three years since they have been placed online ◦ Even not knowing the exact date of their removal from the Internet complicates the calculation of the average lifespan 2

3  Some of the reasons why the web references tend to disappear has to do with: ◦ the absence of a universal definition of web references (Halpin, H., 2011)  URI (Uniform Resource Identifier)  URL (Uniform Resource Locator)  URN (Uniform Resource Name)  or is a completely new system of identifying in order. ◦ disparity in the division of types of web references (Meyer zu Eissen, S.; Stein, B., 2004; Santini, M., 2007) ◦ inability to, accurately, estimate their lifespan (Ashenfelder, M., 2011) 3

4  short lifespan of web references were noticed in: ◦ Research of graduate papers done at the Department of Information Sciences at the Faculty of Humanities and Social Sciences in Zagreb:  Bauer, A.; Kirin, M.; Turković, M. Web References in Graduate Papers at the Department of Information Sciences at the Faculty of Humanities and Social Sciences in Zagreb. // INFuture2011 – Information Sciences and e-Society”/ Billenness, C.; Hemera, A.; Mateljan, V.; Banek Zorica, M.; Stančić, H.; Seljan, S. (ed.). Zagreb : Department of Information Science, Faculty of Humanities and Social Sciences, University of Zagreb, 2011, pp ◦ used as the initial corpus in this research 4

5  The aim of this article is to: ◦ point out a trend of ‘disappearing’ web references, which are used in scientific papers:  how many of the web references are no longer active?  whether they have been relocated or completely removed from the Internet since accessing the web references during the former research? 5

6  The main hypothesis is: ◦ that there has been an increase in the number of inactive web references within the aforementioned corpus since the conduction of the first research, especially because more than a year has passed.  expects that the highest number of inactive web references can be found in the graduate papers that were written during the first half of the analysed period 6

7  In which domain can the web references that disappear most frequently be found?  Whether the type of the web references, their location and the presence of authors and publishers influence their lifespan?  According to the criteria that the active web references meet, what can be done to insure their longevity? 7

8  reasons why the web references tend to disappear: ◦ the absence of a universal definition of web references ; ◦ disparity in the division of types of web references ; ◦ inability to, accurately, estimate their lifespan 8

10  The research was based on the analysis of data that was collected in the previous research: ◦ of graduate papers done at the Department of Information Sciences at the Faculty of Humanities and Social Sciences in Zagreb:  Bauer, A.; Kirin, M.; Turković, M. Web References in Graduate Papers at the Department of Information Sciences at the Faculty of Humanities and Social Sciences in Zagreb. // INFuture2011 – Information Sciences and e- Society”/ Billenness, C.; Hemera, A.; Mateljan, V.; Banek Zorica, M.; Stančić, H.; Seljan, S. (ed.). Zagreb : Department of Information Science, Faculty of Humanities and Social Sciences, University of Zagreb, 2011, pp  used as the initial corpus in this research 10

11  The corpus included: ◦ a set of 362 graduate papers,  available online in the Digital Repository of the Faculty Library, ◦ in the period , ◦ 1947 web references were extracted  Study of the lifespan of web references conducted by the end of January in the year 2013 ◦ comparison of data recorded in:  June 2011 and  January

13  362 graduate papers  included 6525 references, ◦ 1947 (29.8 %) were web references, were analysed 13

14 The overall percentage of active and inactive web references  the results show ◦ by the end of June 2011:  781 (40.1%) web references were unavailable ◦ by the end of January 2013:  922 (47.3 %) web references were unavailable ◦ inactive web references increases for 7.2 %, 14

15 The change of inactive web references (from 2011 to 2013) 15

17 The type of Web sites: The presence of Authors and Publishers:  non-scientific, commercial: ◦ 432 (46.8 %)  educational, cultural and scientific institutions: ◦ 263 (28.5 %)  undefined : ◦ 223 (24.2 %)  Without author : ◦ 657 (71.3 %)  Without publisher : ◦ 848 (92.0 %) 17

18  improve the citing system ◦ stricter, more formal obligation, ◦ required to list all the necessary bibliographical data  relocation the reference ◦ making it accessible through a redirection  citing more URL addresses for the same reference  adding extra identificator : ◦ permalink  for dynamic web sites or ◦ the digital object identifier (DOI)  for the publications published by publishing houses 18

19  Research show: ◦ increase of inactive web references in researched period ◦ According to the type of references :  inactive are the most non-scientific, commercial references  But also substantial amount of educational, cultural and scientific institutions have inactive web references ◦ lack of authors and publishers among inactive web references 19
