Integrated information literacy instruction throughout graduate school supports students as they transition into the role of researcher, but information literacy instruction aimed specifically at mathematics graduate students is not widely studied. This paper reports on the results of a survey of mathematics librarians, which found that a majority of respondents are teaching information literacy classes to mathematics graduate students. Further analysis explores the demographics of both the librarians and students, the skills and resources taught, whether there was faculty-librarian collaboration, and if instruction was assessed.
