Browsing the Hopkins Maps

  • The Browse page lists all the online Hopkins volumes in chronological order based on the official title of the volume. If a volume has been selected for scanning but is not yet online, it will be noted as Coming Soon.
  • This page offers two different methods for browsing maps from a volume/year: Index Map and All Plates.
  • Selecting Index Map for any given volume will subsequently display the volume's original index map. Mouse over the index map and click on the specific plate you wish to view. See Navigating the Maps for further help.
  • Selecting All Plates for any given volume will subsequently return a search result comprised of thumbnail views of all the maps in that volume. See Navigating the Maps for further help.
  • Please Note: Some plates are comprised of two plats. On the index map we have identified these plats as an A or B. (e.g., 1A, 1B, 2A, 2B, etc.). The A and B halves are not designated in the index map itself. As you move your cursor over the index map, the browser status bar below will indicate the linked plat.
  • Please read the Navigating the Maps section for directions to navigate and alter the size of the map.
 

Searching the Hopkins Maps

  • Click on the Search link from any Hopkins map page.
  • This search page enables searching over three primary fields: Streets, Municipality, or Land/Water/Other. Note that we no longer can support a building name search.
  • For a Street search, enter part or all of a street name in the search box and select Streets from the adjacent pull-down menu. While a search on ford will only retrieve Ford St., Ford Ave., etc, a search on ford using the wildcard (*), such as ford* will return Fordham, Fording, etc. Street numbers must be searched as both words (ninth) and numbers (9th) for most complete results. Including a street suffix such as st or ave may also be entered to limit search results.
  • For a Municipality search, enter the name of a municipality, such as Pittsburgh, and select Municipality from the adjacent drop-down menu. Most of the areas covered in the Hopkins maps are in Pittsburgh, but some areas are covered that lay outside the city.
  • For a Land/Water/Other search, enter a landmark feature, such as a river name or cemetary, and select Land, Water, Other from the adjacent drop-down menu.
  • You can also just search over all the fields by selecting Anywhere in record.
  • Submit your query. A page showing thumbnail results of plates matching your search will display. The thumbnail indicates the plate number, name of the map volume, and year. The number of results matching your search displays at the top right-hand corner of the page; by default, 20 results are listed on each page. Use the 'Next Results' links at the top and bottom of the list to view additional results if necessary.
  • Click on the thumbnail of the plate you want to view. This will open a new window displaying the map plate. Note that your search term will appear in red in the descriptive information on the left-hand side of the map.
  • Please read the Navigating the Maps section for directions to navigate and alter the size.
  • To return to your previous search results, close the map plate window that opened up. To perform a new search, click on the Search link on the top of the page.
 

Navigating the Hopkins Maps

  • A map plate displays in its own window. The descriptive information about the map plate appears on the left while the map image appears on the right.
  • Note that the map can first be resized to fit within your screen area by dragging the edge of the display box.
  • You have three choices to zoom in on the map. 1) Point and click with your mouse anywhere on the map; this will increase the zooming level. You can keep doing this until you've reached the maximum zoom area. 2) Select the plus or minus buttons at the bottom of the image. 3) Drag the slider arrow to the right to zoom in or to the left to zoom out.
  • To move around in a map, point your mouse on the map plate, hold down the button and drag the map in whichever direction you wish to go (like Google maps).
  • Note that a thumbnail image appears in the top left-hand corner of the image. This is the Navigation View which features a red box that outlines which part of the map is being displayed. It can also be used to navigate the map. Just click on the area of the map you wish to view.
  • To return to the original view of the map, click on the button that contains a partial circle and arrow pointing to 10:00.
  • If you want to view other maps in the same volume, click on the Index Map Link listed in the descriptive information on the left-hand side.
