Data and record collections
Not all facilities have the ability or legal right to provide sensitive information like population databases across the internet. Fortunately, most will suggest limited manual means of verifying if a person is in custody. One of the more popular requests concerns jail archives. Jails and prisons kept registers so everyone "booked" in to the grey bar hotel was recorded, creating unparalleled historical and genealogical sources for researchers and family members alike. Interactive databases are available from many modern courthouses.
