I am hoping that there is someone on the list whose
knowledge of historical sources might help on a user query...
 
I have a user who is interested in establishing a date for a map in
one of our collections.  The title of the map is:  "Map showing the
line of boundary between the US. and British possessions, from the
point where the 49th parallel of N. latitude strikes the Western
coast of the continent "to the middle of the channel which separates
the continent from Vancouver's Island and thence southerly through
the middle of said channel" etc. to Fuca's Straits, in accordance
with Treaty of June 15th, 1846 " and is marked as being  litho'ed by
Bowen and Co., Philadelphia.
 
In Penfold's "Maps and Plans in the Public Record Office.  v.2:
America and West Indies, there is an item listed which may be the
map in question [Item #429, p 81, dated 1871].  However Penfold's
notation reverts to ellipsis after the words "  ...  British
Possessions  .... " in the title, so the user is not absolutely sure
that this is the same map we have in the collection.
 
My query would be whether anyone has access to the CIS US Serial Set
Index  and Carto-Bibliography of Maps, 1789-1969, and whether
the user could get confirmation from this source for the date of the
map?  A photocopy of the entry for this map, if found in one of the
volumes of the index/carto-bib, would also be useful.
 
With thanks,
