Editing Cigarette card (section)

==Classification and cataloguing==
The system devised to codify 19th Century American tobacco issues has its origin in the 'American Card Catalog' (ACC), written by Jefferson Burdick. Burdick listed the [[American Tobacco Company|American Tobacco]] cards in one section, broken down by companies that issued the card series and by the types of cards. The 19th Century issues were prefixed with 'N' (N1-N694) and the 20th with 'T'. (T1-T235).<ref>Forbes, R and Mitchell, T, (1999) 'American Tobacco Cards: Price Guide and Checklist', Virginia: Tuff Stuff Books</ref>

===The World Tobacco Index (WTI)===
The World Tobacco Index (WTI), published by the Cartophilic Society of Great Britain (CSGB),<ref>The Cartophilic Society of Great Britain (2000) 'The (New) World Tobacco Issues Index: Part 1', London: The Cartophilic Society of Gt. Britain Ltd.</ref> lists all known tobacco issues from around the world and is still being updated today on reports of new finds. Using a similar alphanumeric system, it assigns a code based on the name of manufacturer, rather than the century in which the cards were issued. For example, Burdick's N2 'Celebrated American Indian Chiefs' by [[Allen & Ginter]] is listed as A400-030 (a), with the larger N42 series listed as A400-030 (b).<ref>{{Cite web |url=http://www.csgb.co.uk/nnindex.htm |title=Cartophilic Society (CSGB) |access-date=2002-10-22 |archive-url=https://web.archive.org/web/20021022024852/http://www.csgb.co.uk/nnindex.htm |archive-date=2002-10-22 |url-status=live }}</ref>
