Tip 30. If possible, gain access to closed stacks
Some libraries prevent users from accessing the bookshelves directly. They require users to order books from computers or manual Reader Slips; library staff then deliver the books to readers in reading rooms.
This system works well when you know the specific source you want; but sometimes you need to browse the shelves to find the information you need.
For example, you might want to browse for relevant articles in a law journal series.
If browsing the journals will save you time, then ask the librarian for permission to access the stacks.
A good relationship with your librarian comes in handy here.
