What's New

Version 2.0.0

In addition to updating and streamlining the app's interface, multiple bug fixes were implemented. A browse by category option was also added, bringing the app more in line with the HeinOnline mobile interface. Users are still able to retrieve documents by citation, search across all subscribed collections using advanced searching techniques, view and download image-based PDFs, browse content by title, access tables of contents for easy volume navigation, and email PDFs.

Ratings and Reviews

I now love it!


I love Heinonline and I love working on my iPad, so I love having this app. This new update just fixed my biggest problem with the app - downloading PDFs is much simpler now. Thanks for that! I have to play around with it a bit more before I give it five stars, but definitely four stars. (Five for Heinonline itself!)

Horrible app for an otherwise valuable service


Search function returns entire documents with no ability to jump to relevant sections. Search results are unsorted and have no indication of relevance. Browsing is impossible because titles all start with database name and are therefore subdivisions are all indistinguishable from each other. Quite literally useless.
