We want to use the footer from LibGuides (http://libguides.library.arizona.edu/ABE501-ResearchMethods)

Apologies for not realizing footer content on other springshare tools is out of date. We need a few updates to the links/content to match what is on new.library:

Remove "Tel" from the phone number and style: (520) 621-6442
Change Library Policies to just Policies and link should point to: http://new.library.arizona.edu/policies
Change Employment to Job opportunities and link should point to: http://new.library.arizona.edu/jobs

I see you updated the links, but "Employment" should be changed to "Job opportunities"
