Based on copies that have been preserved in the National and University Library, archival documents, early library inventories and catalogues, and accession logs, this article examines the presence of works by prominent French, English, and American philosophers and political philosophers in the Ljubljana lyceum library’s collection in the last decades of the eighteenth century and the first half of the nineteenth century. It also presents sources that testify to the influence of imperial censorship policies and legislation on the acquisition, recording, and lending of banned literature in the library until 1848, and provides information on individuals and institutions that kept works by banned authors in their personal collections before they became part of the Ljubljana lyceum library. Na podlagi izvodov, ki so se ohranili v Narodni in univerzitetni knjižnici, arhivskih dokumentov, zgodnjih popisov in katalogov zbirke ter akcesijskih dnevnikov članek raziskuje prisotnost del nekaterih prominentnejših prepo-vedanih francoskih, angleških in ameriških filozofov ter političnih filozofov v zbirki ljubljanske licejske knjižnice v zadnjih desetletjih 18. in v prvi polovici 19. stoletja. Predstavlja tudi vire, ki pričajo o vplivu cesarskih cenzurnih politik in zakonodaje na pridobivanje, evidentiranje in izposojo prepovedane literature v licejski knjižnici do leta 1848, ter prinaša podatke o posameznikih in ustanovah, ki so prepovedane avtorje oziroma njihova dela hranili v osebnih zbirkah, preden so te postale del knjižnice ljubljanskega liceja.
