Identify the part of the research report where the following passage falls:

The researchers analyzed all the news stories of each issue of The Catalyst starting from 1986 up to 2010, with the exception of the special issues released and the issues without dates available in the university archives. There were no recorded issues of The Catalyst in the year 1989 and 1990 due to problems within the publication while there were no issues for the year 1999 at the archives during the time of the coding. News roundups and news bits in every issue are also not included in this particular study but would focus on the stories in the news section and sports section.
