Archive File Formats
ZIP files can compress data and therefore save time and space, and make downloading software faster. These files normally have a ".zip" extension and can generally be opened with the default software installed on your computer.
Amazon Kindle Formats (AZW, AZW3, KF8)
Amazon Kindle Formats are proprietary e-book formats developed by Amazon for the Kindle e-reader. These files can also be opened on computers, tablets or smartphones that have the Amazon Kindle App (www) installed.
Electronic Publication Format (EPUB)
EPUB format is an electronic book format that can be opened in most e-readers, tablets and mobile devices (except for the Kindle, which uses a different file format). These files can also be read on computers, but may require specialized software such as Adobe Digital Editions (www) or the Kobo App (www).
Mobipocket Format (MOBI)
MOBI is an e-book format used by the Mobipocket Reader and the Amazon Kindle e-reader, as well as e-book applications on smartphones and tablets. MOBI files can also be accessed on computers, but may require specialized software. E-books in this format have either a .mobi or a .prc filename extension.
Machine-Readable Cataloging (MARC 21) Format
MARC 21 is a format commonly used by library computer systems to organize and exchange information about library items such as publications. For a detailed description of this format, please visit the MARC 21 Standards site (www).
Since April of 2006, Library and Archives Canada (LAC) has been creating download files of MARC 21 bibliographic records for each issue of the Weekly Checklist of Canadian Government Publications. The records in the download file are in the form of a continuous delimited text file intended for importation into catalogue applications that support the MARC 21 data format and MARC editors. They are made available on the Government of Canada Publications Web site in association with the Weekly Checklist issue listing the publications associated with the records contained in the file.
LAC creates MARC 21 bibliographic records for all monographs and new serial titles in hard copy and electronic formats. New download files are added to the Government of Canada Publications Web site as cataloguing for a given Weekly Checklist issue is completed by LAC. The time required for this varies according to the number of publications listed in a given issue.
