Sofia - User Guide

This option groups several editions in a single result (most recent or oldest copy/different formats), and it avoids duplicates. The Group Editions option is set by default.

Search results may be sorted by relevance. One of Sofia’s unique features is to provide three types of relevance sorting:

1. Best match: priority is given to the number of times a word appears in the item. Items where the keyword appears most often come up first in the results list.
2. Recency: priority is given to the publication date of items. However, date is not the only indicator for this type of sorting. Do not confuse it  with sorting by date (most recent).
3. Libraries: priority is given to items from the user’s library collection.  

Other sorting options with the discovery tool Sofia :

• Author (A to Z): search results are sorted by alphabetical order according to the author’s family name and given name.
• Date (most recent): search results are sorted according to the publication date of the item (most recent to oldest).
• Date (oldest): search results are sorted according to the publication date of the item (oldest to the most recent).
• Most held: search results are sorted according to the number of international libraries that hold the item. The most held item is ranked first, and the least held is ranked last.
