Are non-circulating books shelved in a special place? HOLLIS says,
Non-circulating books are not shelved separetly; they should be in the Widener stacks, shelved by call number as usual.
Sometimes HOLLIS does not indicate if an item is available or not. If the item is part of a series, that information is usually found under the series title. If there is no series title, it's best to come to Widener and check the shelf. If the item is not on the shelf where it's supposed to be, tell the staff member at the stacks entrance, and he/she will institute a search for it.
