iDiscover includes records for articles and books that are available thanks to the University having subscribed to them, and additionally thanks to their having been deposited under "electronic legal deposit". Separate records for the same articles and books are included in iDiscover. Records for the articles and books deposited under electronic legal deposit display above the records for the same articles and books that have been subscribed.
When you view the records initially in the results display, notice which records include the text "Online access restricted to designated PCs in the main + UL affiliated libraries". Unless you are on a PC that is dedicated for use of electronic legal deposit material, the link will take you to blank page that will then produce a "Connection timed out" message as no connection can be made to the content from any other PC or device. Note also that if you are viewing the full record for the article or book, a link may be included in the "View online" section of the record that reads "Link to online resource". This link will similarly only lead to a blank page and the "Connection timed out" message.
For successful access to the electronic legal deposit material please use a designated PC. Information on Electronic legal deposit is provided by the ELD LibGuide which includes guidance about finding ELD material in iDiscover.
