Catalyst, the JHU Libraries catalog, is a great tool. With it, you can find books about study skills, maps of Maryland, and action movies. Besides all the great search capabilities, there are two very useful pages hidden in plain sight on Catalyst’s home page that you may want to bookmark.
Reserves gives you access to the reserves sections at 7 different JHU Libraries locations. MSEL is there; also listed are Columbia Center, Institute of the History of Medicine, Montgomery LRC, SAIS, School of Medicine, and Washington LRC. If you’re wondering where some of those places are, never fear!
Other Resources lists all the different JHU Libraries locations with their addresses, phone numbers, and links to their homepages. Also listed on that page are links to JHSearch, FindIt, and the different interlibrary loan systems for the different libraries.
I’ve bookmarked both pages on my office computer and the computer in the Reference Office. I hope you find these pages useful, too.
