Ahava, your first example can be correct if the map is historical in nature, but I would not just use it if a map is say from the 1960s and you want to cover that time period. But we have many examples when a map depicts historical events and then: $$a [name of place] $$x History $$y [chronological subdivision] $$v Maps is correct. However, I would always recommend have $$a [name of place] $$v Maps as that would co-locate all maps of one place together.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Our classification department doesn't usually add subject headings to maps, so the department head asked me to check with the experts (you all). Her question: Is this kind of string correct: $$a [name of place] $$x History $$y [chronological subdivision] $$v Maps Or does it need to be divided into 2 separate subjects: 1. $$a [name of place] $$x History $$y [chronological subdivision] 2. $$a [name of place] $$v Maps Thanks for your help, * Ahava [cid:image001.jpg@01D9297D.98C83A10]<http://www.nli.org.il/> Dr. Ahava Cohen |Head Cataloguing Section Mobile: +972-54-549-3644 The National Library of Israel, Jerusalem [log in to unmask]<mailto:[log in to unmask]> | www.nli.org.il<http://web.nli.org.il/sites/NLI/English/Pages/default.aspx> [cid:image002.png@01D9297D.98C83A10]<http://www.facebook.com/NationalLibraryIsrael> [cid:image003.png@01D9297D.98C83A10] <http://www.youtube.com/user/NLI2010/featured> [cid:image004.png@01D9297D.98C83A10] <http://instagram.com/nli_israel> [cid:image005.png@01D9297D.98C83A10] <http://www.flickr.com/photos/64126959@N03/collections/>
