Actually the @ symbol should be searchable. The Authority File Comparison Rules say to "retain" the "commercial at sign", i.e., @, when doing normalization for NACO access points. That could mean that search terms entered without the @ would fail if the AAP includes an @, especially in systems which index only the AAP and not variant access points.

Early during RDA implementation I had to ask PSD about an author (I believe a women academic in Malaysia), who had taken to writing her name with the “@” character.  This is how it appeared on her book and on her professional website (which was part of a university faculty page).  PSD said to use the “@” and not to worry about it being unsearchable.


I suggest the “rule” is that if the author wants to do something “unusual” , it isn’t for us to overrule them.  We transcribe their names, we don’t dictate  their names (though in some countries, the government does have law regulating names which we need to be aware of).

Subject: Re: [PCCLIST] Constructing Artist's Access Point: Real Name vs. Twitter Name (with or without @ or At ?)


Hi Ed:


That's a tough one.  


One way to resolve this is to contact the person and ask her about her preferences, and also check into whether or not the @ is a part of nome de guerre (it certainly looks to be, but only the author and the Shadow know). 


Failing that, I'd take the t.p. of the book-in-hand at face value:


1000 @AKU_MATU

4000 At AKU_MATU


4001 Warden, Allison


If this gives formulation gives you the jitters, remember that we still have the option of provisional authorities.

What would be the proper way to establish this person's access point?  The person's real name is Allison Warden, but goes artistically by @AKU_MATU or AKU_MATU (I don't understand whether @ is part of the name).  Should this be?

100 0_  @AKU_MATU ǂc (Artist)
100 0_  AKU_MATU ǂc (Artist)
100 0_  At AKU_MATU ǂc (Artist)
100 1_ Warden, Allison

(with the other forms as 400 fields).  And are those spacing underscores okay in access points?

The person has these usages found in two published items.

1)   A book, which is a collection of the author's Twitter poems I am cataloging:
Title page, cover, spine:      by @AKU_MATU
Page 5:      Inupiaq rapper, writer, activist, and performance artist Allison Warden, who performs as AKU-MATU, ... (and page 6 makes a reference to her as simply "Warden")
Very end of book:     ... by Allison Warden, @AKU_MATU

2)  A book (I don't have a copy): "Unsettled : Art + Environment Conference 2017":
Title page (according to the 245 field): contributors, ... Allison Warden, ...

In regards to this conference book, there is a website (, which states:
Allison Warden:  Allison Warden (Inupiaq) is a performance artist, Twitter poet, and rapper whose stage name is AKU-MATU.

I don't have any experience with Twitter, so I don't know if the ampersand is simply a part of the user's Twitter address or is part of the user name or is part of some technical coding.  In the conference book, the person's real name is used on the title page, and that was carried over to the conference's website.  Note that the book of poems and the website make reference to the person as someone who performs under AKU_MATU (without 'at' or @).

There is an authority record for a similar name:  "@librarykris (Librarian),  1974-"  I assume the qualifier was added in order to identify the name as a person since the name is not a regular type of name and someone might think it represents a corporate body or other entity.  Thus, I am suggesting "(Artist)" in my record.

By the way, in OCLC Connexion it is not possible to search by keyword or by browse on the ampersand.  I found the @librarykris example by searching under "At" in a 400 field.
