Downloading ITS•MARC Bibliographic Data

Downloading via web browser: Downloading via the web is typically a two-step process: download records and save to an output file, then upload or import into your local system. For most users, Z39.50 is more convenient because it allows you to search your local database before searching ITS•MARC or other public sources. When used with a cataloging application like BiblioFile, Z39.50 also allows you to perform a "cascaded" search according to your own hierarchy of trusted sources and then edit the records in one application.
Searching via the web browser does have a few advantages over most cataloging applications except BiblioFile*:
- Boolean (combination) search option
- Begins-with searching for text terms (title, author, subject)
- Ability to search notes
- Display of cover art and other content
* BiblioFile supports Boolean, begins-with, notes, and numerous additional search types for both bibliographic and authority records. It also displays cover art, although not other forms of content viewable on the web.
Downloading ITS•MARC Authority Data
ITS•MARC authority records can only be downloaded via Z39.50, not from a web browser.
