These classes ensured librarians and teachers would be proficient in how to use POWER Library resources - statewide catalog and interlibrary loan system, chat reference services, online reference databases, and how to scan and use digitized resources - in order to show students and the general public how to use them. Trainers used a combination of online documentation, in-person or webinar events, and online recorded videos.  This mix of methods responded to the diverse schedules and often limited availability on the part of librarians and teachers. 

The ACCESS PENNSYLVANIA statewide online catalog serves the public, librarians and inmates in state corrections institutions.  Known in the POWER Library as "Books, Movies and More" it includes records from public libraries across the state, saving over one million dollars in purchase costs annually. The public may browse the statewide catalog collection of over 8 million titles of physical and electronic materials available from public, academic, special collection and high school libraries.  Librarians use the statewide catalog to request interlibrary loans for titles not available in local or system collections. The statewide catalog also serves as a large repository of cataloging records. Pennsylvania experienced a statewide stay-at-home order starting in March of 2020 and libraries were mostly closed through June.  As a result, all interlibrary loan activity came to a halt for a period this year because staff were not able to retrieve titles from library collections.

The POWER Library PA Photos and Documents service is an online searchable archive of scanned images and documents representing the rich history and cultural heritage of Pennsylvania. It supports the needs of students by offering primary source materials that support reports and homework assignments.  Nearly 2 million pages of scanned content are searchable by subject or contributing institution.  PA Photos and Documents collections are harvested for inclusion in the Digital Public Library of America (dp.la), making them available for viewing from a national archive. The PA State Archives also participates in the POWER Library, posting collections from over 33 state departments including Agriculture, Education, Health, and Justice. 

In 2019, the POWER Library digital archives continued its migration to a new software platform, using the opens-source Islandora.  By June 30, 2020 all collections were migrated from the previous system.  The location remains the same however, and the archives are available at https://powerlibrary.org/collections/. 

The POWER Library portal is designed to be a one-stop location for online library services available to all residents of Pennsylvania. The URL www.powerlibary.org connects users to Books, Movies and More (the statewide catalog), Chat with a Librarian (24/7 virtual reference), e-resource subscriptions for personal, educational and business use, and PA Photos and Documents, a digital archive of materials by, for, and about Pennsylvania.

To respond quickly to COVID-19 conditions, in 2019 HSLC updated the Find a PA Library tool.  This is a lookup that allows residents to enter a Pennsylvania city or zip code, and receive a list of public libraries that are closest and their status as re-opening plans proceeded.  For example, a library user could learn whether his or her library was closed, or had re-opened book drops, initiated curbside pickup, or offered computer reservations. In another pandemic response, over 300 copyright-free titles were added to the For Librarians section which enabled librarians and teachers to select children's books for online read-aloud activities (such as Story Hour) without violating copyright restrictions.
