Title: Real Measurements for Libraries in an Internet Age: A report on the Normative Data Project
1Real Measurements for Libraries in an Internet
Age A report on the Normative Data Project

Molyneux Chief Statistician SirsiDynix Feb. 2,
2006
2What are libraries most worried about?
- Sustaining Relevance
- Millennial user behavioral mutations
- Balancing print, electronic and new services and
resources - Understanding Diversity
- E-Learning and Distance Education challenges
- Justifying growth and projects Measures not
Stats - Understanding mutating (not changing) usage
patterns info not data - Building community partnerships with authority
- Building for the future and not repairing the
present - Productivity and shifting staff resources
- Budgets and Fundraising
SURVIVAL
3Big Questions
- How do we gain insights into changes in our
ecology through our usability and user behavior
studies, and our trend insights as shown through
our statistics and measurements? - Can we really know the underlying reasons for
users interactions with library services? - Can we easily and cheaply compare ourselves to
other libraries, other agencies, or communities? - Can we back up our qualitative stories with
quantitative measurements and data - proofs? - If we had the proofs, would it help our
strategies, fundraising and tactical
implementations? - Are we happy with the present?
4Acting like a business but being a library
- Knowing Customers like Wal?Mart
- Giving service like Nordstrom
- Being as efficient as GE
- Delivering an experience like Amazon
- Having the budget of Google
- Living the brand

- Data, charts and graphs help but dry
- Debate Argument a little confrontational
- Conversation a lot of effort, scales poorly
- Narrative storytelling captures the energy of
the population and persists - Read

- Start with understanding the users in terms of
their real - needs, preferences, and desires
- goals and aspirations
- expectations and assumptions
- values and their beliefs
- tolerance for risk and change

13Personas
- Personas are understood through discovery by
- Gathering data to identify possible anchors
- Observing behavior
- Pattern emergence in narrative

15Personas
- Personas are hypothetical representations of a
natural grouping of users that drive
decision-making for development projects. - They are defined by goals.
- They focus on what is valuable to the user and
subsequently on how he or she behaves. - They are not Stereotypes or Archetypes

Goals Help team build the base infrastructure
for .NET products. Construct the base set of
services that ship with the product and compose
the core of a distributed framework for hosting
distributed services. Add queuing semantics and
associated locking, classification and routing of
messages, subscriptions, efficient filtering,
fan-out, etc., to the server. Integrate new
distributed communication semantics to the
existing SQL Server programming model.
Demonstrate ability to communicate and work well
with other teams. Usage Scenario Henry has
been around long enough to build a solid network
of resources to call when he has specific
questions about products or programs. He often
learns about new technologies or processes
through casual conversation with his friends and
coworkers in the hallway. He uses Yahoo! for
general information gathering because he likes
the simplicity of the site design and the breadth
of information available. The Portal is not
his start pagehe usually just types in the URL
directly. He rarely reads the content on the
first page because he doesn't want to know what's
going on with general companywide PR information.
He's somewhat cynical about "companywide"
internal releases and dislikes company politics.
However, on a personal level, he does want to
know about the schedules that the applications
are on so he can plan. He's frustrated that
there's no place you can go to find product
information all in one spot. Info-Seeking
Behavior When Henry needs specific information,
he generally e-mails or phones a friend. He is a
member of about 15 different DLs that used to be
manageable, but now he finds it increasingly
difficult to keep up. He typically uses the
Portal to search for internal information across
the companywide intranet or to find other
internal sites. He comes to the portal about
four-five times a week by typing in the URL and
stays for less than 15 minutes at a time. He
rarely, if ever, goes to there to find general
information about the company or the industry as
a whole. He uses internal databases to find
internal information on products or code. If he's
frustrated by something, he'll go there and find
solutions rather than go outside to support or to
a dot-com. "You used to have to drill down pretty
deep to find personalized information, but now
it's easier." He tends to bookmark pages in the
portal because he hates having to go 5 levels
down. He'll use that bookmark until it breaks,
then he has to research it again. He would like
to have favorites on the portal.

17The Future
- Public Library Pilot Project
- Libraries in rural, urban and suburban
Northeastern U.S. and Canada to start - March through May, 2005
- Leveraging proven techniques for understanding
complex markets (Cynefin Centre) - Follow up to cover the broader U.S.A. and global
marketplace - Follow through for Academic (ARL, ACRL, LibQual
and COUNTER, etc.) - K-12 School personas can follow later
23
18The Future
- In summary, by seeing the world through the lens
of the customer, we create an - Opportunity to increase customer satisfaction and
return visits - Opportunity for everyone in the organization to
work to achieve the same goals, efficiently, and
an - Opportunity to have a clear, and achievable
direction. - Pandoras Box Exciting but a little dangerous

30Mommy Marcie
- Caucasian American, married, 33, two children,
two and four, lives in suburbs (pop.50-100,000),
Northwest, bachelors degree, household income of
60K, works part-time as a substitute teacher. - A typical day at the library Mother and
children typically drive to the library. The four
year old girl is in a reading group. The two
year old attends storytelling. Each Monday they
go to the library to attend the reading group and
to hear a story. Afterwards they use the time to
check out new books, videos or DVDs for
children, as well as to find time to look for any
adult materials. - Sample Scenario Marcy is interested in taking
her 2 year old to storytime and in getting
learning to read materials for her 4 year old.
In preparation for an upcoming library trip,
Marcie logs on to the library website and selects
recipe and craft books for herself, and verifies
the storytime for her toddlers. While at the
library, she picks up her reserved books, takes
her kids to storytime, may select some additional
materials, and request assistance from a
librarian on the topic of phonics. - Information-seeking behavior She typically
doesnt have time to use the computer at the
library. At the library she is usually busy
looking after the children either participating
in a reading group session, or attending a
storytelling session. She uses the computer at
home to put materials on reserve for herself or
if she knows exactly what she wants for the kids.
She picks up the books, DVDs or videos when she
is leaving the library. She uses the library
website to hear more about upcoming events. - Ultimate goal She wants her child to learn to
read and to discover new ideas in a safe,
informed setting. She wants her children to be
exposed to books early on even when they dont
know how to read yet. She wants to be able to
find time to meet some of their own needs knowing
their children are safe. - Frustrations Not finding librarians who can
help the children to learn to read, is troubled
by reduced library hours (nights and weekends),
and wants to have an easy way to know about
upcoming events on the website. - Work activities Part-time employment.
- Computer skills, knowledge and abilities Has an
up-to-date home computer and uses the library
website. - Technology attributes Positive towards
technologyearly mainstream adopter. - Communicating She uses the phone, email, IM.
- Market size and influence Significant Market
presence-- - Demographic/online attributes 83 of parents
with minor children use the Internet 63 of
college educated women who have infant children
work 5.4 million stay at home Moms in 2003.
31Mommy Marcie
- Quotes
- Id like to see the library website be more
useful, to make it easier to find library events
and resourcesId really like to have that sort
of information sent to methat would be great! - Can my library institute an early reading
program, or help me find relevant resources,
whether online or in the library? - Actual anecdote like I said, Im towing my
two-year-old around, and if Ive got -- you know,
if its -- searching for something on the
computer involves sitting there for half an hour,
well, Im trying to keep my two-year-old in
check. She does not sit well. Shes trying to
run around and play, do something to occupy her.
If Im having to go through too many lists, or if
I dont know exactly where Im going to need to
be looking for something, I end up looking
through everything to find the information I
want, then we might as well just go home and Id
try while shes sleeping, you know? - References Pew Internet and the American Life

Messaging?)

33Jennifer
A typical day at the library The parent assists
the teenager in using the library website. This
is usually done at home, after the teenager has
reviewed what is available on the Internet. The
parent is coming in after the research has begun.
Once they identify the books they need they will
put them on reserve or check to see if they are
available. Once there, they may decide to browse
the young adult library collection (if they have
time). Otherwise they are focused on getting the
materials for the project. Once they have the
material they need, they leave. The parent will
likely have to bring other children to the
library at the same time. They will be pulled in
multiple directions, looking after their younger
children and their teens. She wants to use the
library as more of a recreational facility for
herself, but given her busy lifestyle, she is
unable to. When she is there, the library
becomes a social setting. She talks with the
staff socially, and enjoys the interaction. Inform
ation-seeking behavior The info seeking
behavior of this parent is utilitarian although
theyd prefer it to be more recreational. They
start by working with the teenager to browse
available information from the library online at
home. When they go to the library they go there
to find specific items (books, music) or to
browse newspapers or journals. They may help a
child to post a community notice on a bulletin
board at the entrance to the Library for example,
Scouts or Babysitting. At the library the adult
may be responsible for signing the teenager on to
the computer equipment. Ultimate goal The
parents want their children to know how to use
the library and to use the best sources of
materials to complete a project. They also may
see the library as a great location to post
availability to baby-sit, or to announce a
community event. Frustrations Students
needing regular permission from the adult to use
the computer equipment. Safety with respect to
sites used. Noisy students. The parent wants to
know whats happening in the library, but is not
often notified of events they may be interested
in. They want communication pushed out to them
in a form they find useful. Work activities
Dual-income household both parents work.
Computer skills, knowledge and abilities Has a
shared space home computer and is aware of the
library website. Both parent and teenager are
computer-literate. Technology attributes
Positive towards technology. Communicating
She uses the phone, Instant Messenger and Email.
They prefer the phone or Email but chat with
their teens over IM. Market size and influence
This group represents a large portion of the tax
paying base within a community and is a great
person for the library to have as an advocate
because she is active and likes using the
library. While frustrated with some issues at
the library, its not for sure whether she sees
her current interaction as a negative. Does she
really want to not have to go to the
library? Demographic/online attributes The
parent user is typically female, white, educated,
married, over 35 and uses a branch library. IM
and text messaging keep teens in touch with their
parents. Most teens use shared computers at home
and a growing number log on from libraries,
school, and other locations. 67 of parents of
online teens believe the Internet is a good thing
for their child but are concerned about the
safety of it. 90 of teens who go online say
that other family members also use the computer.
Many parents use various methods of filtering and
monitoring teen computer use. (See High School
Anchor for other related demographic data).

- Quotes
- X I took them - it was a couple of weeks ago,
it was national library week as a matter of fact
- it was very vibrant that day. My twin boys
wanted to go downstairs, they had magic shows as
part of a promotion for national libraries week,
and my 13-year-old had to do a project so he was
working upstairs while his brothers were
downstairs so it was very, very busy. As a
matter of fact they had to bump a meeting from
downstairs upstairs, the Girl Scouts were meeting
that day too. So there were hundreds of people
at the library. It was a good experience. It
was a great day in the community. - INT And what were the boys looking for? You
said one of them was working on a project. - X A science project.
- INT A science project. And did he find the
information he was looking for? - X Yes, he did. Theres reference materials and
a few books that he had to cite. - INT Were you downstairs with the twins and you
sent him up? - X Yeah. I was doing the bouncing up and down
trick. - INT You went upstairs and what happened? What
did you do? - X He got all his work done.
- INT Do you know if he found all the stuff on
his own? Did he talk to a librarian? - X The librarians are very helpful with him.
Hell go up and ask. Theyre always willing to
point him in the right direction. He didnt need
the computers because any computer stuff we
pretty much do at home. - INT Im trying to get to actual stories. Let
me think. So you come to the library every day?
And are you particularly - References Pew Internet and the American Life
Project Forrester Research - Some parents noted that they dont always have a
working computer at home and then they take their
child to the library to use the computer to
complete a school assignment. We also came across
several teenagers that do not have a computer at
home.
35Jennifer
- SirsiDynix Product Considerations for Jennifer
- Opportunities
- To get information to this user in a delivery
format that meets their lifestyle (RSS, IM, Text,
E-mail). This person wants information on
community events, education related events for
students, dates due, new books of interest (ala
iTunes, Amazon). - School Rooms/Rooms has the opportunity to help
this parents teenager to do more research from
home.but does the parent want services that make
it so that kids dont even need to go to library.
She likes the library and feels the need for
teaching her kids the same values.
36Tasha Learner
- A typical day at the library Goes to the
library to use the computer. Is working on a
project that requires the Internet, as well as
completing her reading with books she doesnt
own. Is likely using the computer to print a
report or to create marketing collateral. - Information-seeking behavior Makes a specific
point of going to the library to complete her
project. She consults with a reference librarian
to ensure she has a good starting place and then
uses the online catalog and the Internet to
source both electronic and hardcopy information
sources. She prints out materials to work with
them. She is aware that some sources are more
appropriate than others, but consults with the
librarians to ensure she has the best possible
sources. - Ultimate goal Wants to complete her project by
ensuring all the appropriate resources are used
and needs to use the library computer to do so. - Frustrations Not finding all the sources she
needs. Having to get off the computer within a
particular timeframe. Inconsistencies in which
library has which resources, e.g. dictionaries,
inaccessible librarians i.e. not available when
you need them. - Work activities Part-time student, part-time
worker. Student in a night school or
junior/community college - Computer skills, knowledge and abilities Does
not own a computer but is a computer user. Knows
how to search on the Internet and is familiar
with the librarys website. Easily authors and
prints using productivity tools. - Technology attributes Positive towards
technology. - Communicating She uses the phone and may have
access to Email. - Market size and influence Although less than 8
of patrons fall into this demographic, it is a
target demographic for our customers and the
general public in the library as a community
benefactor. - Demographic/online attributes Very likely earns
less than 30k per year is likely Hispanic or
African American. Does not own a computer and is
likely to have a cell phone.
