I-Wikisource yilayibrari yedijithali ye-intanethi yemithombo yombhalo yasimahla kwi-wiki, eqhutywa yiWikimedia Foundation. I-Wikisource ligama leprojekthi iyonke kunye negama lomzekelo ngamnye waloo projekthi (umzekelo ngamnye udla ngokumela ulwimi olwahlukileyo); ezininzi Wikisources yenza iprojekthi iyonke ye Wikisource. Injongo yale projekthi kukubamba zonke iintlobo zombhalo wasimahla, ngeelwimi ezininzi, kunye neenguqulelo. Ekuqaleni yayiyilwe njengendawo yokugcina imibhalo yembali eluncedo okanye ebalulekileyo (umbhalo wayo wokuqala yayiyi-Déclaration universelle des Droits de l’Homme), iye yanda ukuze ibe lithala leencwadi elinomxholo jikelele. Le projekthi yaqala ngokusesikweni ngoNovemba 24, 2003 phantsi kwegama elithi Project Sourceberg, umdlalo weqonga okwiProject Gutenberg edumileyo. Igama elithi Wikisource lamkelwa kamva kulo nyaka kwaye lafumana igama layo lesizinda kwiinyanga ezisixhenxe kamva. Le projekthi inemisebenzi ekwidomeyini yoluntu okanye enelayisensi simahla; imisebenzi epapashwe ngobungcali okanye amaxwebhu embali, hayi iimveliso ezingamampunge; kwaye zinokuqinisekiswa. Uqinisekiso lwenziwe ngaphandle kweintanethi ekuqaleni, okanye ngokuthemba ukuthembeka kwamanye amathala eencwadi edijithali. Ngoku imisebenzi ixhaswa ngokuskena kwe-intanethi nge-ProofreadPage extension, eqinisekisa ukuthembeka kunye nokuchaneka kweetekisi zeprojekthi. Ezinye ii-Wikisources, nganye imele ulwimi oluthile, ngoku ivumela kuphela imisebenzi exhaswa ngeskeni. Ngelixa uninzi lwengqokelela yayo iyimibhalo, iWikisource iyonke ibamba ezinye imidiya, ukusuka kwiicomics ukuya kwifilimu ukuya kwiincwadi ezimanyelwayo. Ezinye ii-Wikisources zivumela i-annotations eyenziwe ngumsebenzisi, ngokuxhomekeke kwimigaqo-nkqubo ethile ye-Wikisource ekuthethwa ngayo. Le projekthi iye yagxekwa ngenxa yokungathembeki kodwa ikwakhankanywa yimibutho efana neNational Archives and Records Administration.
