By 2009, each of the nine councils of the Empire State Library Network (ESLN) had created and maintained its own regional digital collections site for member libraries and other organizations. These included Tools of History, CNY Heritage, WNY Legacy, CDLC Digital Collections, Long Island Memories, North Country Digital History, Digital Metro, Finger Lakes and Genesee River Valley (FLAG) Heritage and Hudson River Valley Heritage.
These nine digital collections sites were harvested and searchable with a multi-site server product hosted at www.newyorkheritage.org. That product has been discontinued since 2012, but eight of the councils have consolidated into a single digital collections site, www.nyheritage.org, built on a hosted instance of OCLC’s CONTENTdm.
In 2017, New York Heritage Digital Collections began rolling out a new version of the website that features more contextual information on the institutions and collections that comprise the digital repository.
