===Dates and reprints===
{{anchor|Dates and reprints of older publications}}

Date a book that is identically reprinted or printed-on-demand to the first date in which the edition became available. For example, if an edition of a book was first released in 2005 with an identical reprinting in 2007, date it to 2005. If substantive changes were made in a reprint, sometimes marked on the verso with "Reprinted with corrections", note the edition and append the corrected reprint year to it (e.g. "1st ed. reprinted with corrections 2005").

Editors should be aware that older sources (especially those in the public domain) are sometimes republished with modern publication dates; treat these as new publications. When this occurs and the citation style being used requires it, cite {{em|both}} the new and original publication dates, e.g.:

* {{cite book |last=Darwin |first=Charles |date=1964 |orig-date=1859 |title=On the Origin of Species |edition=facsimile of 1st |publisher= Harvard University Press}}

This is done automatically in the {{tl|citation}} and {{tl|cite book}} templates when you use the {{para|orig-date}} parameter.

Alternatively, information about the reprint can be appended as a textual note:

* {{cite book |last=Boole |first=George |title=An Investigation of the Laws of Thought on Which Are Founded the Mathematical Theories of Logic and Probabilities |date=1854 |publisher= Macmillan}} Reprinted with corrections, Dover Publications, New York, NY, 1958.
