As needed
Continue to monitor new and changed resources for inclusion. Keep the guides in mind whenever a new database (or a link change) is announced, when new editions of books (especially reference books) become available, etc. Each time a course is being offered, allow the instructor to review any relevant course guides so that he or she can suggest any updates.
After major changes
Check your guide on multiple devices with different screen sizes to ensure that your guide functions well and important content is still on top. Shrinking and expanding your browser window can show a similar effect of how your guide will appear on a smaller or narrower screen. Use the publishing checklist to ensure that your guide still meets STLCC standards.
