ALA-LC (American Library Association – Library of Congress) is a set of standards forromanization, the representation of text in otherwriting systems using theLatin script.

The system is used to represent bibliographic information by North American libraries and the British Library (for acquisitions since 1975)^[1]and in publications throughout the English-speaking world.

TheAnglo-American Cataloguing Rules require catalogers to romanizeaccess points from their non-Roman originals.^[2] However, as theMARC standards have been expanded to allow records containingUnicode characters,^[3][4]many cataloguers now include bibliographic data in both Roman and original scripts. The emergingResource Description and Access continues many of AACR's recommendations but refers to the process as "transliteration" rather than "Romanization."^[5]

The ALA-LC Romanization includes over 70 romanization tables.^[6] Here are some examples of tables:

• ACherokee Romanization table was created by the LC and ALA in 2012 and subsequently approved by the Cherokee Tri-Council meeting inCherokee, North Carolina. It was the first ALA-LC Romanization table for a Native American syllabary.^[7]
• TheChinese Romanization table used theWade–Giles transliteration system until 1997, when the Library of Congress (LC) announced a decision to switch to thePinyin system.^[8]
