Isijengamazwi somtapowolwazi siyincwadi yokubhalisa zonke izinto zomchazamibhalo ezitholakala kumtapolwazi noma iqembu lemitapolwazi, efana noxhoxho lwemitapolwazi  esezindaweni ezihlukene. Isijengamazwi semitapolwazi siyiqembu sibizwa isijengamazwi sobumbano. Isibhalo somchazamibhalo kungaba yinoma yini enokwaziswa (njengencwadi, amahele wesiCikizi, imifanekiso, nezithako zamabalazwe njll) nethathwa njengesibhalo somtapolwazi, noma isibhalo semitapolwazi eyiqembu, noma isijengamazwi esikhongciwe (sekhasilwebu) uma nje lubalulekile esijengamazwini nakubasebenzisi bomtapolwazi.

 Impokophelo 
Ngonyaka we-1841, u-Antonio Genesio Maria Panizzi kanye no-Charles Ammi Cutter ngowe-1876 baqala umsebenzi owahlahla indlela ekuchasiseni imithetho yokujengamazwi yokuqala eyacabaywa ngokuqondene nezinongo zesumbono. U-Cutter yena waziveza ngokusobala izimpokophelo zohlelo lomchazamibhalo encwadini yakhe ethi Rules for a Printed Dictionary Catalog. Ngokuka-Cutter, lezo zimookophelo yilezi

1. ukwenza umuntu athole incwadi enalezi zici ezilandelayo ezaziwayo (impokophelo yokuhlonza):
 umlobi
 isihlokosiqu
 isihlokondaba
 usuku lokushicilelwa

2. ukuveza okukhona emtapowolwazi (impokophelo yokuthungatha)
 ngokomlobi oveziwe
 ngokwesihlokondaba esiveziwe
 ngokohlobo lwencwadi eveziwe

3. Ukulekelela ekukhetheni incwadi (impokophelo ecubungulayo)
 ngokohlelo lwayo (ngokomchazamibhalo)
 ngokwesidwambu sayo (ngokwesihloko)

Lezi zimpokophelo zisengawashelwa ngokwezincasiselo zanamuhla formulated throughout the 20th century.

Ezinye izingqalabutho zalomkhakha kwakunguShiyali Ramamrita Ranganathan noSeymour Lubetzky.

Izimpokophelo zika-Cutter zabuyekezwa nguLubertzky kanye neNgqungquthela yeMithetho yokuJengamazwi (CCP) eyayise Paris ngowe- 1960/1961, nokwaphumela eMthethweni yaseParis yokuJengamazwi (PP).

Isigabavu sakamuva sokuchazisa izinsebenzo zesijengamazwi somtapowolwazi senziwa ngowe-1998 ngeziMfuneko ezisebenzayo zeziQoshwa zomchazamibhalo (FRBR), ezichazisa imisebenzi emine yomsebenzisi: ukuthola, ukuhlonza, ukukhetha, nokuzuza.
