OCD meaning in Academic & Science ?

Answer: What is Oxford Classical Dictionary mean?

The Oxford Classical Dictionary (OCD) is generally considered "the best one-volume dictionary on antiquity," an encyclopedic work in English consisting of articles relating to classical antiquity and its civilizations. It was first published in 1949 (OCD1 or OCD), edited by Max Cary with the assistance of H. J. Rose, H. P. Harvey, and Alexander Souter. A second edition followed in 1970 (OCD2), edited by Nicholas G. L. Hammond and H. H. Scullard, and a third edition in 1996 (OCD3), edited by Simon Hornblower and Antony Spawforth. A revised third edition was released in 2003, which is nearly identical to the previous third edition. A fourth edition was published in 2012 (OCD4), edited by Simon Hornblower, Antony Spawforth, and Esther Eidinow. In 2016, a fully digital edition launched online, edited by Sander Goldberg (2013–2017) and Tim Whitmarsh (2018–present). Continuously updated on a monthly basis, this edition incorporates all 6,300 entries from OCD4 (which are being updated on a rolling basis) as well as newly commissioned entries, and features multimedia content and freely accessible maps of the ancient world.

The OCD's over 6,400 non-blind articles cover everything from the daily life of the ancient Greeks and Romans to their geography, religion, and their historical figures.
