Reference librarians work with many different classes in many different ways. Here are some examples, and the ideal lead time we need to prep (and to avoid calendaring conflicts!):

• The Library's Syllabus Statement
• A customized Course Guide 
  • 2 weeks lead time
  • You can also link to existing general guides like this one. 
• ​A short meet & greet with a librarian, and intro to/refresher on library research (5-20 minutes)
  • 1 week lead time
  • Useful for consultation-intensive classes
• A deeper dive into information literacy, or a guided working session (60-90 minutes)
  • 2-4 weeks lead time
  • A deeper dive into information literacy [such as: tips & tricks of specific databases; scavenger hunt for library sources; a discussion around source evaluation, etc.]
• Small group consultations (in which a librarian meets with 1-4 students at once)
  • Self-scheduled with the student(s), but it's helpful for us to know if you're directing the whole class to make appointments with their liaison librarian.
  • It's often helpful for the liaison librarian to come in for a few minutes during class to introduce themselves to the students and to briefly address some commonly asked questions.
  • You can put the link to your liaison librarian's scheduler in your syllabus or on Moodle (e.g. https://go.carleton.edu/ioliveira)

...or something else! Always feel free to reach out, no matter when it is.
