NEW: LOC Collections App
To celebrate the 220th anniversary of its founding, the Library of Congress today announced the release of the LOC Collections app, the premiere mobile app that puts the national library’s digital collections in the hands of users everywhere.
In addition to providing an easy, accessible way to search and explore the Library’s growing digital collections, LOC Collections allows users to curate personal galleries of items in the Library’s collections for their own reference and for sharing with others. Items currently featured on the app include audio recordings, books, videos, manuscripts, maps, newspapers, notated music, periodicals, photos, prints, and drawings.
“The Library of Congress collection can now fit in your pocket,” said Librarian of Congress Carla Hayden. “The Library started 220 years ago with 740 books and three maps. Today, that collection has grown to make us the largest library in the world and a storehouse of our national history. It’s been our goal to throw open our treasure chest and help every American connect to the Library of Congress. The LOC Collections app is a uniquely personal, easy new way to explore the nation’s library.”
Users can currently find the app for iPhone and iPad at the Library’s website or the iTunes store. An Android version of the app is slated for release later in 2020.

ITC’s (GST/HST) – Beyond the Basics
One of the objectives of a value-added tax system is to simplify the administration of taxes, and this is accomplished by taxing almost everything and everyone, but allowing input tax credits (ITCs) for those who are not considered to be the final consumer of supplies. While many accounting and finance professionals understand the basic rules for claiming ITCs for GST/HST paid on property and services acquired in relation to an organization’s commercial activities, few have the time to explore some of the more complex issues associated with ITCs.
