Polyfoils are documents that can have multiple levels of interconnected content. They allow for coordinated information to be presented on different surfaces or levels. Some key Polyfoils discussed include: - Gear Polyfoils that present two documents on perpendicular arcs with related content. - Transformer Polyfoils that render documents as packages that can be opened to allow different views and input. - User choice Polyfoils that present pairwise comparisons of content to allow users to construct unique views over time. - Polyfoil ecosystems allow documents to be linked through content branches so information can take on new relationships. Special purpose Polyfoils include Law Polyfoils to avoid orphan footnotes, Crypto Polyfoils to segregate sensitive content

2. Polyfoil Sequences: Distinctive

gPs are gear Polyfoils that run 2 documents on joint
othogonal arcs, with coordinated content on congruent levels.
tPs are Transformer Polyfoils that render e-docs as packages in
4D that open up, afford 2D input, and offer 3D external views.
uPs are user choice Polyfoils that present pairwise comparison
for users to construct unique views in time, rather than space.
Polyfoil Ecosystems are documents linked together by content
branches. Editors and librarians organize branches to
generate new approaches to information.
These and other distinctive Polyfoils will be explored in more
detail in Part 3.

3. gP 'gear' Sequences
Gear Polyfoils use two documents with
common subject and structure, though not
aligned point to point, page to page.
They are in perpendicular
positions. Gear function
polyfoils have content
anchors that a control
module uses to broker
related content.
Both documents
are loaded. A
content anchor
on the front text
locates a related
content anchor
on the other.

4. tP Transformer Sequences
Transformer Polyfoils let users bring content into their viewport
from any side, rather than chasing it sideways. Windows let
observers see
granular detail,
without access
to the entire text.
Sections are parallel.Transformers are suited for scientific
communication, which is usually a
package, not a story.
Users open up
panels, to
access full
content.

5. Transformer Sweet Spot: Science
Scientific Polyfoils render e-docs as packages that open, to
optimize user assessment of quality, and permit views of e-
docs in scientific 4D subject space.
Current scientific article electronic publishing is suboptimal, for
users and providers. Users can't access different parts of online
articles to determine quality prior to purchase. Obviously pub-
lishers don't provide content before purchase.
tPs constructed on polyhedrons are a solution to this dilemma.
An Archimedian solid called a rhombicuboctahedron is ideal.
1. Rhombicuboctahedrons can be flattened into 2D arrays.
Their rectilinear faces provide an input template, similar to
science poster sections. Articles can be of any length.

6. Transformer Sweet Spot: Science
2. When closed, a rhombicuboctahedron's surfaces provide
portal views of each section's content. The random snippet
in view provides enough information for users to estimate
article quality, but not enough to replace buying the article.
3. Reading takes place inside the shape, with 2.5D surfaces
that can reveal subject space around them, termed 4D.

7. Information content like ads, news media, short fiction, and
publicity gets consumed as a commodity. Consumers have
many choices. Youtube users select from a column. Scanning
Amazon's sponsored products is row-based. News readers
select from rows & columns. Consumer choice analysis can
improve readers' experience. Instead of pulling a single unique
news story from an array, pairwise comparison works better.
People make more satisfying selections given a succession of
binary choices.
Descriptive analysis of consumer choice finds people select a
weakly preferred product successfully by comparing product
pairs. Behavioral analysis comes to the same conclusion. As
we examine products individually, we consider attributes that
are irrelevant for choosing between them. Faced with many
products simultaneously, we compare a single attribute across
all of them, and often miss the most important factor.
But comparing pairs is a happy medium. We can contrast
multiple attributes easily. Perception researchers describe this
as a contrast effect, which is effective in determining identity.
uP 'user choice' Sequences

8. uP 'pairwise' comparison
Most retail environments,
including online news portals,
cluster user choices - and
clutter user options.
Physical newspapers present
many stories close together,
but digital news portals show
little more than headlines.
Consumer choice research
says more information, but only
in pairs, is better.
Polyfoils offer two sequences
next to each other. They're a
happy medium for digital news.
A user replaces the one less
preferred with an alternative,
considers, replaces one or
both again, until they choose.
A flat picture of many products
becomes a multi-dimensional
structure in time.

9. uP Sweet Spot: News
Pairwise comparisons empower online news users with the
amount of information physical newspapers offer. Their uniform
formatting speeds substitution downloads. Instead of clicking on
little more than a headline to read an article, users read 2 or more
paragraphs first. They read more efficiently.

10. Document core sequences are trunks. Polyfoils can have
branches, and these can diverge and reach other documents'
branches or core. Science, politics, history, and critical
discourses currently siloed by hyper-specialization can be
opened to new relationships. Tangents extended to others
form Polyfoil ecosystems.
A Polyfoil branch may extend, developing meaning along
a growing panel sequence, until it joins to another document.
This is a profound change in document environments. It
transforms an editor's or librarian's role. Editors are writing
mechanics. Polyfoils let them plan traffic. Librarians guard
book identities. Polyfoils let them build book relationships.
Polyfoil Ecosystems

11. Ecosystem
sweet spot:
Academic
Libraries
Tofay's Academic Libraries
seek meaning. Historically
central to campus life, they're
reduced to subscription doyens.
Academic librarians can use
semantic marking of content, to
find common subject focus of
different works. Publishing does
not encourage specialtists to
recognize subfield connections.
Speciality siloes need Polyfoil
meta-librarians to develop con-
nections in idea ecosystems.
Most scientific fields can't break
the reductionist approach that
is easier to fund and publish.
Interdisplinary understanding,
critical to future prosperity, is
the domain of information
specialists: librarians.

12. Special Purpose Polyfoils
Law Polyfoils avoid orphan footnotes, which are otherwise
an insurmountable obstactle to legal journals wanting to
publish electronic, thus reflowable, documents.
Crypto Polyfoils are electronic documents that contain
more than a single level of information confidentiality. Highly
sensitive content is segregated on Polyfoil surfaces, pro-
tected by cryptographic keys. Ordinary users use a public
core text.
Project Management Polyfoils serve leaders and others
working on projects. Leaders gain an overview of tasks
and schedules across the entire project, and workers can
see how their functions fit into larger flows. Things don't fall
between the cracks, such as a task two sectors think the
other handles. Project transparency is efficient.
A special version of this Polyfoil suits film/TV productions.

13. Law Polyfoils
A typical law journal article has footnotes on >1/4 of each page.
Saved stubs render
as armnotes.
When the user
saves, it appears
adjacent to the core
anchor.
If users change
view scale, the text
reflows, and arm-
notes remain next to
their anchor.
The online Yale Law
Journal presents itself
framed with blank panels.
A polyfoil writer triggers a
stub and inputs content.

14. Crypto-Polyfoil
A crypto-Polyfoil is a core public document enhaced by oPs
and/or other Polyfoil that egress from core content anchors with
related, confidential content. These Polyfoils cannot be
accessed without decryption keys, which apply to classification
levels and audiences.
Decryption processes decrease productivity. Most readers do not
want to frequently engage private keys. With crypto-Polyfoils,
they don't have to. Core content flows uneventfully. Only with
private keys, classification status, and sufficient motivation, can
one access confidential material in these Polyfoils.

15. A Polyfoil project management document has time on the
scrolled axis. The core has an overview of output stages, which
may be multiple columns or rows.
In many projects, outputs grow in number over time. Their
graph is pyramid-shaped. Interactions between sectors
increase with time as well. This causes ordinary chart break-
downs. Polyfoil project management documents overcome
this. Should they present a sector's sequential outputs on a
horizontal time axis, then in later time periods, if the output
grows complex, additional panels are added vertically.
Other sectors are reached by scrolling vertically or clicking a
map. An overview is reached by zooming out. This displays all
sectors. The overall view is an array of linear paths, rotating
around the origin, along polar coordinates that establish time.
Film/TV projects fit Polyfoil templates, with different depart-
ments reached on different Polyfoil paths. These are described
more in Part 3.
