Data on prisoners, book holdings, book circulation, and share of prison library users for individual U.S. state and federal prison libraries for source-determined years from about 1868 to 1940. The cross-section data are not fully reconciled across years. Some years include data from multiple sources. Selection of sources and matching of facilities across years is necessary to use these data as panel data.
U.S. prison libraries in 1875 held an estimated 6 volumes per prisoner and circulated yearly 34 volumes per prisoner. These figures changed little through 1938. Comparing state prison libraries with public libraries in 1875 indicates that prison libraries held six times more books per prisoner than public libraries held books per adult in the U.S as a whole. Prison libraries’ relatively large book holdings per prisoner and circulation per prisoner are consistent findings from the nineteenth century to the present.
The prison library data for 1875 nearly covers the universe of identified state prisons. The union of records (including general population census records) identifies 53 state prisons in 1875. Among these institutions, 39 had prison libraries. Specific data indicate that 9 of the remaining 14 institutions did not have prison libraries. The state prison reported in Atlanta, Georgia (476 prisoners estimated for 1875) almost surely did not have a prison library. Most of these prisoners were probably dispersed in leased work gangs and on state farms. The other four prisons for which no information is available are small, with the state prison in Olympia, Washington (36 prisoners estimated for 1875) being the largest. Those prisons probably didn’t have a library, and even if one did, the library was surely very small. Overall, specific data on volumes in prison libraries (or absence of a prison library) covers 97% of state prisoners in 1875.
