We have not been live with Vega for too long and have been asked several times by customers for this and especially an option for alphabetical sorting

A title A-Z or Z-A sort option is very useful and can help make searching faster.

The ability to have an alphabetical sort (or better yet index search) would make it easier to find a specific known work rather than browse through irrelevant records

REQUEST: Our patrons are asking for the ability to sort search results by Author or by Title, in addition to Date and Relevancy.

Feature Details: 
Job Stories: As a Vega User I would like to be able to sort my search results in alphabetical and reverse alphabetical Order by Title and Author. 

Acceptance Criteria: 
Sort Options are Added for: 
Title A-Z
Title Z-A
Author A-Z
Author Z-A
Sorting implies that initial articles are not considered in sort: a, an, the, etc.
Sort Options can be translated in all Language Files
Relevancy Remains the Default Sort applied to all searches
Sort Options are listed in alphabetical order in the Sort Selection Menu.

It would also be nice to be able to sort items alphabetically when doing, say, an author search as well.

Sorting by author, title, date, and relevancy is an expected function by our users and one that greatly improves results.

Sorting by author is common practice for our patrons and is often how we provide our reader's advisory experience. This

Being able to sort by author or title can significantly increase accessibility and usability of a list. It improves the user's experience.

For continuity of user experience, author and title sorts are common practice. It provides an additional access point to group search results.

Author sort makes a huge difference when searching a common title. Making it easy for patrons to find what they want improves the user experience.

When you are looking for a series it can be nice to be able to sort results by author.
