If your interest is in second-hand Ordnance Survey maps, the Charles Close Society issued the first 'informal listing' of dealers in such material in December 2001.

FUTURE:

• American Book Prices Current ([Washington, D.C.:] Bancroft-Parkman). [Founded 1895. From 2005 it has been issued on a single cumulative CD-ROM, covering the period from 1975. The earlier printed form was an annual listing of material coming through the world's major auction houses, with indexes at irregular intervals. See in Part I (MSS) under 'Maps & Charts' and Part II (Books) under 'Atlas' and 'Maps' (arranged by region). As its webpage explains: 'ABPC is not just a transcribed record of titles and prices, copied unquestioningly from the season's auction catalogues. ABPC is the standard tool used by dealers, appraisers, auction houses, scholars and tax authorities. It is, moreover, the only work in English in which each listing of printed material has been checked as to title, format, date of publication, edition, and limitation.']

• Antique Map Price Guide (AMPG). [Offering current valuations on maps from 1475 to 1850 - issued on Flash Drive [previously annual editions, in 24 geographically-defined volumes plus an index volume. Started in 2010 - from map- world.com]

• Antique Map Price Record. [Published, from 2012, by OldMaps.com (Curt and Marti Griggs), as a priced listing of over 150,000 records of maps that passed through selected auction houses and dealers - as a result of the merging of the 138,000 entries on the former Antique Map Price Record (linked to 40,000 high-resolution images, e.g. from the the Library of Congress and David Rumsey Collection) and the 60,000 on OldMaps.com's 'Antique Map Price Guide'. What had been a cumulative annual listing from 1983 (on CD-ROM from 2002) will now be accessible via online subscription. Formerly: David C. Jolly, Antique Maps, Sea Charts, City Views, Celestial Charts and Battle Plans: Price Guide and Collectors' Handbook, produced latterly by Jon & Bernice Rosenthal, and from 2002-11 by Jeremy Pool.]

• Book Auction Records (Folkestone: Dawson). [Founded 1902. Annual listing of material coming through the world's major auction houses, with indexes at irregular intervals. Ceased publication after 1997. Cartographic entries grouped under 'atlases' and a separate section 'printed maps, charts and plans'. This was dropped for the 1997 volume.]

• Imago Mundi. The International Journal for the History of Cartography. [Section 6 of the annual 'Chronicle' (by Ashley Baynton-Williams) lists (without giving prices) rare and important items that have come up for sale, via auctions or dealers. Section 5 lists notable acquisitions, arranged by institution.]

• Paulus Swaen Old Maps (an image archive of 20,000 maps in high resolution; "The auction results and estimated value are freely available for our registered users")

H!BCoR Grading System for Antique maps, old prints, books, posters offers an 'Antique Map Price and high resolution image source' to 'auction results of 10000+ antique maps...'. You have to register for estimated prices or high resolution images.

A review in The Portolan 79 (Winter 2010), pp.43-4 by Leigh Lockwood about 'Map World's Catalogue of Antique Maps 1472-1850', produced a reply from its publisher and that, in turn, one from Jeremy Pool, producer of the 'Antique Map Price Record', to which the former had been compared (pp.45-6).

Barnebys is [February 2014] promising 'a complete overview of the auction house market ... salesroom and online auctions from around the world ... Search 70,000-100,000 unique items on a daily basis'. There is no specific category for maps; the nearest are 'Art, Prints' or 'Books'. Most of the items found via a search for 'map' were not relevant.

If you want to compare the prices that are being asked for maps, check out the inventories of the dealers listed on the 'web images' page under 'Larger Image Sites (dealers).
