Library StacksWelcome to the Lehigh County Historical Society's Research Library and Archives. We invite you to explore our excellent collection of local and regional history and extensive genealogy holdings. Here, at one of Pennsylvania's most significant archives, you will find a wealth of resource material for the serious and casual historian and the genealogist: books, maps, newspapers, photographs, oral histories, church and social records, personal and family papers, business documents and numerous county records. To facilitate your research, our reading room offers skilled staff and comfortable quarters. Our Research Library accommodates requests for on-site look-ups only.  A look-up is defined as looking up information about one named person, topic or document in a specific collection or record group. For more information and to request a look-up, please complete our "Look-up" Request Form.


New Research Library Use Procedures during COVID-19

Effective July 13th, our Research Library resources will be available to researchers by appointment only.  In order to provide quality service to our Research Library patrons, while continuing to prevent the spread of coronavirus in our community, we will be allowing researchers access to our collections through the following procedures. While Library resources are available, the Lehigh Valley Heritage Museum is temporarily closed to general visitors.  

Researchers are required to make appointments for sessions from 10:00 a.m. to 12:30 p.m., or from 1:00 p.m. to 3:30 p.m. Tuesday through Friday.  Each appointment is for one person only.  We require that you request the records and documents that you want to research in advance.  This will allow us to process your request quickly and efficiently.  

Our Library Reading Room is not spacious enough to safely accommodate all Library patrons at this time.  The archives will be open on a modified basis.  Please call us at 610-435-1074 to schedule an appointment.  Once your appointment is confirmed, submit a list of the research materials you need via email to j_youngken@lehighvalleyheritagemuseum.org, or mail your request to the attention of Jill Youngken.  Please keep in mind that we need sufficient time before your appointment to prepare materials you have requested. 

A photocopy request form must be filled out to request photocopies, which must be made no less than 30 minutes prior to the end of your research session.  Copy fees are .75 cents per letter-size page, .80 cents per legal-size page, and $1.50 per ledger-size page.  We do not allow scanners or camera in research areas.  Payment is required immediately after copies are made.

The spread of Covid-19 infection remains a real and serious threat to human health.  Therefore, our institution takes social distancing, the proper wearing of face masks, hand washing and all other Center for Disease Control guidelines seriously.  To insure the safety and health of our visitors, we conduct temperature checks and require all visitors to answer a list of routine and prudent questions during the Covid-19 Pandemic.  Our goal is to keep everyone safe and healthy.  We have a legal responsibility to make our facilities clean and safe by conducting daily and hourly cleaning.  Your cooperation and understanding is appreciated.

We look forward to welcoming everyone. We want to make your visit safe and enjoyable.  To do so, we require that you wear a face mask, and practice social distancing that conforms to the Pennsylvania Governor’s directive, and CDC guidelines while using the Library resources. For additional questions or information, please call Joseph Garrera at 610-435-1074.  

Admission is Free to members, non-member adults pay $8.00 per visit.  We appreciate the opportunity to be of service, and thank you for your interest.  


In case of inclement weather please call 610-435-1074 to be sure we’re open.


The General Harry C. Trexler Collection Finding Aid provides an overview of our collection of materials related to General Harry C. Trexler (April 17, 1854-November 17, 1933).  Born in Easton, Pennsylvania, he was an American industrialist, conservationist, and major philanthropist.  In 1885, Trexler married Mary M. Mosser.  They were married for 48 years, until his death in 1933 from injuries suffered in an automobile accident.  Mary died one year later.  They had no children.  Through a charitable trust Trexler established in his Will, his wealth continues to provide a major benefit to the people and community of Lehigh County, Pennsylvania. 

Our collection of Trexler materials described in the Finding Aid includes ledgers, land records, maps, scrapbooks, photographs, and ephemera related to Trexler’s life and the legacy he left behind.  Our Finding Aid is designed to guide “in-house” research.  This collection is not digitized for off-site viewing or research.  Questions should be directed to Jill Youngken, Director of the archives at 610-435-1074 or j_youngken@lehighvalleyheritagemuseum.org 

Thank you for your interest in the life of General Harry C. Trexler.
