Like the majority of the states, Pennsylvania has never completely concentrated her archives. Various groups of material currently administered by a bureau or department, such as the land records in the Land Office, should not be concentrated until they cease to be a part of the Government's daily business. But aside from these, there are tons of non-active files which will some day be moved, when the Archive Division of the State Library can house them. Under such conditions no one can state absolutely and concisely what there is; and as one result of this difficulty, research work that might utilize business documents is severely handicapped.
