SinceОд 1985, the ''BritannicaБританика'' hasима hadчетири four partsдела: the {{lang|la|[[Micropædia]]}}, the {{lang|la|[[Macropædia]]}}, the {{lang|la|[[Propædia]]}}, and aи two-volumeдвотомни indexиндекс. The ''Britannica''{{'s}} articles are found in the {{lang|la|Micro-}} and {{lang|la|Macropædia}}, which encompass 12 and 17 volumes, respectively, each volume having roughly one thousand pages. The 2007 {{lang|la|Macropædia}} has 699 in-depth articles, ranging in length from 2 to 310 pages and having references and named contributors. In contrast, the 2007 {{lang|la|Micropædia}} has roughly 65,000 articles, the vast majority (about 97%) of which contain fewer than 750 words, no references, and no named contributors.<ref name="library_association_1996" /> The {{lang|la|Micropædia}} articles are intended for quick fact-checking and to help in finding more thorough information in the {{lang|la|Macropædia}}. The {{lang|la|Macropædia}} articles are meant both as authoritative, well-written articles on their subjects and as storehouses of information not covered elsewhere.<ref name="kister_1994" /> The longest article (310 pages) is on the United States, and resulted from the merger of the articles on the individual states. A 2013 "Global Edition" of ''Britannica'' contained approximately forty thousand articles.<ref name="store.britannica.com">{{cite web |url=http://store.britannica.com/products/043009100 |title=Britannica Global Edition |url-status = dead|archive-url=https://web.archive.org/web/20140705002524/http://store.britannica.com/products/043009100 |archive-date=5 July 2014 |website=Encyclopædia Britannica Store }}</ref>
Information can be found in the ''Britannica'' by following the [[cross-reference]]s in the {{lang|la|Micropædia}} and {{lang|la|Macropædia}}; however, these are sparse, averaging one cross-reference per page.<ref name="sader_1995" /> Hence, readers are recommended to consult instead the alphabetical index or the {{lang|la|Propædia}}, which organizes the ''Britannica''{{'s}} contents by topic.<ref name="index_preface">{{Cite journal | year = 2007 | title = The New Encyclopædia Britannica | journal = Chicago: Encyclopaedia Britannica Inc | edition= 15th edition, ''Index'' preface| bibcode = 1991neb..book.....G | last1 = Goetz | first1 = Philip W. }}</ref>
