Image Sizes

PTFS Confidential

Challenges• Image Quality, OCR Accuracy• Difficult to achieve high OCR accuracy• Original text quality varies : yellowed paper, bleed through,

faded, bound page curvature• Microfilm quality varies• Dark borders, washed out sections, out of focus• Misc: Scratches, Thumbs, Tape, Staples!!

• Grayscale best, but results in large files sizes

PTFS Confidential

Challenges• Rules for zoning (for clipping) are complicated

to design and execute• Newspaper formats vary widely from title to title

& year to year• Determine zoning rules and consistently follow

Challenges “NDNP Ready”

Imaging & metadata standards, XML packets Massive storage requirements—many, many terabytes of storage File types: TIFF and PDF Browse hierarchy

Determines organization of collection Supports logical presentation

Page & clipping relationships

PTFS Confidential

Solutions

Browse Hierarchy Organized by county/city, then newspaper title, year, month, date Pages and clippings will be presented together

Page & clipping relationship Clippings linked to pages

Archive quality image location Archive quality images transported via USB external drive and backed

up to tape (twice!)

Lessons Learned

• Lots of open communication, between all partners, contractor and sub-contractors

• Start looking for money early, but make sure you have your ducks in a row. Don’t get discouraged.

Lessons Learned• Think of the long term implications of decisions

made at the beginning of the project• Decisions made at the beginning of the project can

have unforeseen, and often huge, implications.

Opportunities

• Fill in gaps in coverage• Orphan papers—publishers and even towns that no

longer exist• “New to us” newspaper titles that haven’t been

located and microfilmed yet
