Thanks for your email. The Countway Library does not have a subscription to UpToDate, although we do offer our users access to resources that provide equivalent information. Foremost among these is DynaMed, an evidence-based clinical reference resource available at http://nrs.harvard.edu/urn-3:hul.eresource:dynamedl. If you are an HMS student, you can access UpToDate through Education Computing. For more information, please visit this webpage: https://collaborate.hms.harvard.edu/display/CETHelp/UpToDate+Mobile
If you have questions about using DynaMed, or would like to talk to a reference librarian about similar resources, please contact the Countway Reference staff at (617) 432-2134 or firstname.lastname@example.org.
