* Staff verify request in OCLC. If they have an OCLC number and it matches, they may not look further to see that it is a popular title and available in other editions. The same applies for copies available in microformats.
** If in a collected works version ILL staff may not know; would typically require interview with ILL staff or reference librarian. This frequently does not take place with electronic requesting.
† Patrons prefer print copy to microformat copy and they will try to request if print copy is available. For purposes of this study ILL staff were asked to let the requests proceed.
