Conservation and Access : 1914 Portland Atlas now on Digital Commons

Along with the 1882 Goodwin Atlas, which we have recently conserved, digitally scanned, and posted on the Library’s Digital Commons site,  now you may view, research, and download the 1914 Richards Atlas of Portland. Like Goodwin, Richards is a footprint atlas, which means that each built structure and land parcel is outlined on this series of maps- which includes every street in the city of Portland, along with contiguous portions of South Portland and Casco Bay islands.

Just as 1882 shows us the pre-Deering merger Portland, 1914 shows Portland in its second decade as the merged city with amended street name changes.

Notice the difference in the pond’s contour, compared to now, as well as that of Forest Avenue. At the top center is the old Portland Stoneware Company.

The original Richards Atlas has long been a very popular item in the Portland Room’s collections, such that our reference copy required some major conservation work, prior to digitization and continued research access. All the conservation work was done in the Portland Room.

Richards Atlas plates were removed from an unsalvageable binding, and thoroughly cleaned before any further treatments.

Removing the embrittled hinges, and preparing the plate halves to be joined in registration with the map’s lines.

Above and below: Richards Atlas plates had been on facing pages, with wide gutter-margins in between. For this project, the facing pages were joined together with acid-free, long-fibered Japanese kozo tissue and methylcellulose adhesive from the verso sides of the composite plate. Thus the viewing experience is now seamless- both in person, and in the digital scans.

In the digitized version of the Richards Atlas, we encoded the names of the maps’ respective Portland neighborhoods of coverage. Thus, the maps can be searched by neighborhood. Major city landmarks are also included, to help ease the research.
